Источник

In the modern world, we regularly encounter the words million and billion, and businesses, governments, astronomers and journalists often think in the millions, billions or even trillions. However, the word million has been around in English only since the late fourteenth century. The word billion was not introduced in the French language until the fifteenth century and didn’t find its way into English until the end of the seventeenth century, which is fairly late in the history of counting. What words were used before this time to talk about large numbers? This article looks at how we started using million and billion and how the meaning of billion has changed.

Before the Words Million and Billion

In fact, the largest number with a single-word name in ancient Greek was 10,000. It was called murios and borrowed into Late Latin as myrias. From myrias we get the English word myriad meaning “an extremely large number or amount”. The ancients also had the “myriad myriad” (10,000 × 10,000) or one hundred million. Larger numbers were described in more roundabout ways or by using mathematical notation; indeed, one million is expressed in Latin as decies centena milia or 10 × 100 × 1,000, and Archimedes (3rd century BCE) had to establish his own system of mathematical notation in order to systematically express numbers larger than the “myriad”. He explains this system in The Sand Reckoner, a treatise that sets out to quantify all the grains of sand in the universe in order to challenge the idea that such a quantity was too large to be counted.

What Exactly Is a Billion?

For those who were taught numbers before the 1970s, the answer to this question may well have been different depending on where you received your schooling. While it is accepted in English today that one billion equals 10⁹, it is important to be aware, especially when reading older texts, that in the United Kingdom billion hasn’t always meant 10⁹. Until the 1970s, when the United Kingdom officially adopted the American definition of billion, this word represented 10¹² in British English.

This difference resulted from the emergence of two competing systems for naming large numbers. A fifteenth-century mathematician, Nicolas Chuquet, established one system by combining Latin numerical prefixes (bi-, tri-, etc.) with the suffix -illion to form powers of one million. In this system, a billion equals one million times one million (or one million squared, 10¹²) and a trillion equals one million cubed (10¹⁸). This is known as the long scale, which was used in the United Kingdom until they followed the United States in 1974 by officially adopting the short scale, a system born in France in the seventeenth century and popular in the French-speaking world until midway through the nineteenth century. The short scale uses the same names (billion, trillion, quadrillion, etc.) but assigns different values to them, with one billion equalling a thousand million, one trillion equalling a thousand billion, and so forth, the logic being that the prefix attached to -illion represents n in the formula 10³⁽ⁿ⁺¹⁾. For example, quadrillion, with the prefix quadri- meaning “four” is equal to 10³⁽⁴⁺¹⁾ or more simply 10¹⁵. The short scale is used today throughout the English-speaking world, whereas the French language has settled on the long scale, so that an English billion is translated in French as un milliard and a French billion (also called mille milliards or “one thousand milliards” in English) is translated in English as a trillion.
The differences between the long scale and the short scale are summarized in this table:

Number	Short Scale	Long Scale	SI* Prefix	SI Symbol
10⁶	one million	one million	mega-	M
10⁹	one billion	one thousand million or a milliard	giga-	G
10¹²	one trillion	one billion	tera-	T
10¹⁵	one quadrillion	one thousand billion	peta-	P
10¹⁸	one quintillion	one trillion	exa-	E
10²¹	one sextillion	one thousand trillion	zetta-	Z
10²⁴	one septillion	one quadrillion	yotta-	Y
10²⁷	one octillion	one thousand quadrillion
10³⁰	one nonillion	one quintillion

* SI refers to the International System (of Units), a system of measurement widely used in science and international trade.

Abbreviated Forms

People often wonder if there is a correct or best way to abbreviate million and billion when writing about figures.

The most commonly seen short forms for thousand, million, billion and trillion in North America and the United Kingdom, respectively, are outlined in the table below.

Number	North America	United Kingdom	Rarer Forms
thousand	K	k or K	thsnd(.), M
million	M	m	mil(.), mill(.), mln(.), MM
billion	B	bn	bil(.), bill(.), bln(.)
trillion	T	tn	tril(.), trill(.), trn(.), tln(.)

Notice that M appears twice in the table above, to represent both thousand and million. Some (especially older) finance texts use M for thousand and MM for million, which can be a source of confusion as M is now widely used to denote million in North America.

Of the style guides that address spacing in this context, most (AP Stylebook, Chicago Manual of Style, Canadian Style, The Economist Style Guide) say to leave no space (100bn, for example), although it is also common in books and newspaper articles to see the abbreviation preceded by a space.

Since there is no universally accepted way of abbreviating these words, the best practice is to be consistent with whatever system of short forms you choose and to ensure that the meanings of your chosen short forms are clear to your audience—for example by establishing at some point in the text that M stands for million, and so forth. Most style guides agree that it is best to spell out these words in full where possible, and to use the abbreviations where spacing is limited (e.g. in headlines and tables) or when figures are repeated often. The Guardian and The Telegraph spell out thousand, million, etc. in full when referring to people and animals and use the abbreviated forms only when discussing inanimate objects or in financial contexts. Scientific texts, on the other hand, avoid appellations like million, billion and trillion and instead use scientific notation when writing about very large and very small numbers. Scientific notation represents numbers in powers of ten, so that 650 billion can be written as 650 × 10⁹ or as 6.50 × 10¹¹.

Источник

Two naming scales for large numbers have been used in English and other European languages since the early modern era: the long and short scales. Most English variants use the short scale today, but the long scale remains dominant in many non-English-speaking areas, including continental Europe and Spanish-speaking countries in Latin America. These naming procedures are based on taking the number n occurring in 10³ⁿ⁺³ (short scale) or 10⁶ⁿ (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion.

Names of numbers above a trillion are rarely used in practice; such large numbers have practical usage primarily in the scientific domain, where powers of ten are expressed as 10 with a numeric superscript.

Indian English does not use millions, but has its own system of large numbers including lakhs and crores.^[1] English also has many words, such as «zillion», used informally to mean large but unspecified amounts; see indefinite and fictitious numbers.

Apart from million, the words in this list ending with —illion are all derived by adding prefixes (bi-, tri-, etc., derived from Latin) to the stem —illion.^[11] Centillion^[12] appears to be the highest name ending in -«illion» that is included in these dictionaries. Trigintillion, often cited as a word in discussions of names of large numbers, is not included in any of them, nor are any of the names that can easily be created by extending the naming pattern (unvigintillion, duovigintillion, duoquinquagintillion, etc.).

Name	Value	Authorities

Googol	10¹⁰⁰	✓	✓	✓	✓	✓	✓	✓	✓	✓
Googolplex	10^googol (10^10¹⁰⁰)	✓	✓	✓	✓	✓	✓	✓	✓	✓

All of the dictionaries included googol and googolplex, generally crediting it to the Kasner and Newman book and to Kasner’s nephew (see below). None include any higher names in the googol family (googolduplex, etc.). The Oxford English Dictionary comments that googol and googolplex are «not in formal mathematical use».

Usage of names of large numbers

Some names of large numbers, such as million, billion, and trillion, have real referents in human experience, and are encountered in many contexts. At times, the names of large numbers have been forced into common usage as a result of hyperinflation. The highest numerical value banknote ever printed was a note for 1 sextillion pengő (10²¹ or 1 milliard bilpengő as printed) printed in Hungary in 1946. In 2009, Zimbabwe printed a 100 trillion (10¹⁴) Zimbabwean dollar note, which at the time of printing was worth about US$30.^[13]

Names of larger numbers, however, have a tenuous, artificial existence, rarely found outside definitions, lists, and discussions of how large numbers are named. Even well-established names like sextillion are rarely used, since in the context of science, including astronomy, where such large numbers often occur, they are nearly always written using scientific notation. In this notation, powers of ten are expressed as 10 with a numeric superscript, e.g. «The X-ray emission of the radio galaxy is 1.3×10⁴⁵ joules.» When a number such as 10⁴⁵ needs to be referred to in words, it is simply read out as «ten to the forty-fifth». This is easier to say and less ambiguous than «quattuordecillion», which means something different in the long scale and the short scale.

When a number represents a quantity rather than a count, SI prefixes can be used—thus «femtosecond», not «one quadrillionth of a second»—although often powers of ten are used instead of some of the very high and very low prefixes. In some cases, specialized units are used, such as the astronomer’s parsec and light year or the particle physicist’s barn.

Nevertheless, large numbers have an intellectual fascination and are of mathematical interest, and giving them names is one way people try to conceptualize and understand them.

One of the earliest examples of this is The Sand Reckoner, in which Archimedes gave a system for naming large numbers. To do this, he called the numbers up to a myriad myriad (10⁸) «first numbers» and called 10⁸ itself the «unit of the second numbers». Multiples of this unit then became the second numbers, up to this unit taken a myriad myriad times, 10⁸·10⁸=10¹⁶. This became the «unit of the third numbers», whose multiples were the third numbers, and so on. Archimedes continued naming numbers in this way up to a myriad myriad times the unit of the 10⁸-th numbers, i.e. $(10^{8})^{(10^{8})}=10^{8cdot 10^{8}},$ and embedded this construction within another copy of itself to produce names for numbers up to ${displaystyle ((10^{8})^{(10^{8})})^{(10^{8})}=10^{8cdot 10^{16}}.}$ Archimedes then estimated the number of grains of sand that would be required to fill the known universe, and found that it was no more than «one thousand myriad of the eighth numbers» (10⁶³).

Since then, many others have engaged in the pursuit of conceptualizing and naming numbers that have no existence outside the imagination. One motivation for such a pursuit is that attributed to the inventor of the word googol, who was certain that any finite number «had to have a name». Another possible motivation is competition between students in computer programming courses, where a common exercise is that of writing a program to output numbers in the form of English words.^{[citation needed]}

Most names proposed for large numbers belong to systematic schemes which are extensible. Thus, many names for large numbers are simply the result of following a naming system to its logical conclusion—or extending it further.^{[citation needed]}

Origins of the «standard dictionary numbers»

The words bymillion and trimillion were first recorded in 1475 in a manuscript of Jehan Adam. Subsequently, Nicolas Chuquet wrote a book Triparty en la science des nombres which was not published during Chuquet’s lifetime. However, most of it was copied by Estienne de La Roche for a portion of his 1520 book, L’arismetique. Chuquet’s book contains a passage in which he shows a large number marked off into groups of six digits, with the comment:

Ou qui veult le premier point peult signiffier million Le second point byllion Le tiers point tryllion Le quart quadrillion Le cinq^e quyllion Le six^e sixlion Le sept.^e septyllion Le huyt^e ottyllion Le neuf^e nonyllion et ainsi des ault’^s se plus oultre on vouloit preceder

(Or if you prefer the first mark can signify million, the second mark byllion, the third mark tryllion, the fourth quadrillion, the fifth quyillion, the sixth sixlion, the seventh septyllion, the eighth ottyllion, the ninth nonyllion and so on with others as far as you wish to go).

Adam and Chuquet used the long scale of powers of a million; that is, Adam’s bymillion (Chuquet’s byllion) denoted 10¹², and Adam’s trimillion (Chuquet’s tryllion) denoted 10¹⁸.

The googol family

The names googol and googolplex were invented by Edward Kasner’s nephew Milton Sirotta and introduced in Kasner and Newman’s 1940 book Mathematics and the Imagination^[14] in the following passage:

The name «googol» was invented by a child (Dr. Kasner’s nine-year-old nephew) who was asked to think up a name for a very big number, namely 1 with one hundred zeroes after it. He was very certain that this number was not infinite, and therefore equally certain that it had to have a name. At the same time that he suggested «googol» he gave a name for a still larger number: «googolplex.» A googolplex is much larger than a googol, but is still finite, as the inventor of the name was quick to point out. It was first suggested that a googolplex should be 1, followed by writing zeros until you got tired. This is a description of what would happen if one tried to write a googolplex, but different people get tired at different times and it would never do to have Carnera a better mathematician than Dr. Einstein, simply because he had more endurance. The googolplex is, then, a specific finite number, equal to 1 with a googol zeros after it.

Value	Name	Authority
10¹⁰⁰	Googol	Kasner and Newman, dictionaries (see above)
10^googol = 10^10¹⁰⁰	Googolplex	Kasner and Newman, dictionaries (see above)

John Horton Conway and Richard K. Guy^[15] have suggested that N-plex be used as a name for 10^N. This gives rise to the name googolplexplex for 10^googolplex = 10^{10^10¹⁰⁰}. Conway and Guy^[15] have proposed that N-minex be used as a name for 10^−N, giving rise to the name googolminex for the reciprocal of a googolplex, which is written as 10^{-(10¹⁰⁰)}. None of these names are in wide use.

The names googol and googolplex inspired the name of the Internet company Google and its corporate headquarters, the Googleplex, respectively.

Extensions of the standard dictionary numbers

This section illustrates several systems for naming large numbers, and shows how they can be extended past vigintillion.

Traditional British usage assigned new names for each power of one million (the long scale): 1,000,000 = 1 million; 1,000,000² = 1 billion; 1,000,000³ = 1 trillion; and so on. It was adapted from French usage, and is similar to the system that was documented or invented by Chuquet.

Traditional American usage (which was also adapted from French usage but at a later date), Canadian, and modern British usage assign new names for each power of one thousand (the short scale.) Thus, a billion is 1000 × 1000² = 10⁹; a trillion is 1000 × 1000³ = 10¹²; and so forth. Due to its dominance in the financial world (and by the US dollar), this was adopted for official United Nations documents.

Traditional French usage has varied; in 1948, France, which had originally popularized the short scale worldwide, reverted to the long scale.

The term milliard is unambiguous and always means 10⁹. It is seldom seen in American usage and rarely in British usage, but frequently in continental European usage. The term is sometimes attributed to French mathematician Jacques Peletier du Mans circa 1550 (for this reason, the long scale is also known as the Chuquet-Peletier system), but the Oxford English Dictionary states that the term derives from post-Classical Latin term milliartum, which became milliare and then milliart and finally our modern term.

Concerning names ending in -illiard for numbers 10⁶ⁿ⁺³, milliard is certainly in widespread use in languages other than English, but the degree of actual use of the larger terms is questionable. The terms «Milliarde» in German, «miljard» in Dutch, «milyar» in Turkish, and «миллиард,» milliard (transliterated) in Russian, are standard usage when discussing financial topics.

For additional details, see billion and long and short scale.

The naming procedure for large numbers is based on taking the number n occurring in 10³ⁿ⁺³ (short scale) or 10⁶ⁿ (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion. In this way, numbers up to 10^3·999+3 = 10³⁰⁰⁰ (short scale) or 10^6·999 = 10⁵⁹⁹⁴ (long scale) may be named. The choice of roots and the concatenation procedure is that of the standard dictionary numbers if n is 9 or smaller. For larger n (between 10 and 999), prefixes can be constructed based on a system described by Conway and Guy.^[15] Today, sexdecillion and novemdecillion are standard dictionary numbers and, using the same reasoning as Conway and Guy did for the numbers up to nonillion, could probably be used to form acceptable prefixes. The Conway–Guy system for forming prefixes:

	Units	Tens	Hundreds
1	Un	^N Deci	^NX Centi
2	Duo	^MS Viginti	^N Ducenti
3	Tre ^(*)	^NS Triginta	^NS Trecenti
4	Quattuor	^NS Quadraginta	^NS Quadringenti
5	Quinqua	^NS Quinquaginta	^NS Quingenti
6	Se ^(*)	^N Sexaginta	^N Sescenti
7	Septe ^(*)	^N Septuaginta	^N Septingenti
8	Octo	^MX Octoginta	^MX Octingenti
9	Nove ^(*)	Nonaginta	Nongenti

^(*) ^ When preceding a component marked ^S or ^X, «tre» changes to «tres» and «se» to «ses» or «sex»; similarly, when preceding a component marked ^M or ^N, «septe» and «nove» change to «septem» and «novem» or «septen» and «noven».

Since the system of using Latin prefixes will become ambiguous for numbers with exponents of a size which the Romans rarely counted to, like 10^6,000,258, Conway and Guy co-devised with Allan Wechsler the following set of consistent conventions that permit, in principle, the extension of this system indefinitely to provide English short-scale names for any integer whatsoever.^[15] The name of a number 10³ⁿ⁺³, where n is greater than or equal to 1000, is formed by concatenating the names of the numbers of the form 10^3m+3, where m represents each group of comma-separated digits of n, with each but the last «-illion» trimmed to «-illi-«, or, in the case of m = 0, either «-nilli-» or «-nillion».^[15] For example, 10^3,000,012, the 1,000,003rd «-illion» number, equals one «millinillitrillion»; 10^{33,002,010,111}, the 11,000,670,036th «-illion» number, equals one «undecillinilliseptuagintasescentillisestrigintillion»; and 10^{29,629,629,633}, the 9,876,543,210th «-illion» number, equals one «nonilliseseptuagintaoctingentillitresquadragintaquingentillideciducentillion».^[15]

The following table shows number names generated by the system described by Conway and Guy for the short and long scales.^[16]

Don’t abbreviate the word million. Spell it out.

Many people want to abbreviate million, but it opens the door to confusion.

For example, I asked Google for guidance on how to abbreviate million here. As you can see, that got me pages full of conflicting search results.

Abbreviation for Million

When business people read reports and recruiters read resumes, it’s common to see this — $1M.

While recruiters love to see numbers on resumes, they also like them to be accurate (more here) and make sense.

When they see $1M, many readers have no idea if the writer means $1,000 or $1 million. That’s a considerable difference ($999,000, to be exact).

Let’s say you’re talking about sales growth of $1 million. If you use $1M, some of your readers might think sales grew $1,000 instead of $1 million. You go from being a hero to an underperformer without knowing it.

Numbers produce anxiety and confusion in many people. Help them by making your quantifications crystal clear.

If you’re talking millions, use the word — $1 million.

If you’re working on your resume and are desperate for space, use $1MM. It’s understood that “MM” means million. But no, wrong! See the comments below. “MM” won’t work for UK readers. It can mean “billion” there.

ChatGPT likes M, but also suggests mil, MM, and mrd. As you can see, confusion reigns. In one iteration I ran, it acknowledged that “million” provides the most clarity.

Abbreviation for Thousand

If you’re talking thousands, use the number: $1,000.

A single “M” can mean either thousand or million, so that doesn’t work.

Again, if you’re desperate for space, use $1K for $1,000. Most people understand that “K” means thousand. If they don’t, they can Google it and get a straight answer (I checked).

But why use an abbreviation your readers have to Google?

Abbreviation for Billion

Again, don’t.

Spell it — $250 billion.

In English, a “billion” is 1 000 000 000 (a thousand million).

This has always been the case in US English.

In British English, in the past the word “billion” meant a million million. If we wanted to refer to a thousand million, we simply said “thousand million” or more rarely “milliard”. But in 1974 we officially adopted the US practice of using “billion” to mean a thousand million.

The word “milliard” has since gone out of use in British English. It never existed in US English.

Much of the confusion over the usage of these words derives from variants of the word “milliard” remaining in common usage (and meaning a thousand million) in other European languages, e.g. Spanish millardo, French milliard, German milliarde, Polish miliard and Russian миллиард.

Remember these words translate into “billion”. And there is no longer any distinction between British and US usage.
