1,000,000,000 (one billion, short scale; one thousand million or one milliard, one yard,^[1] long scale) is the natural number following 999,999,999 and preceding 1,000,000,001. With a number, «billion» can be abbreviated as b, bil^{[citation needed]} or bn.^[2][3]

In standard form, it is written as 1 × 10⁹. The metric prefix giga indicates 1,000,000,000 times the base unit. Its symbol is G.

One billion years may be called an eon in astronomy or geology.

Previously in British English (but not in American English), the word «billion» referred exclusively to a million millions (1,000,000,000,000). However, this is no longer common, and the word has been used to mean one thousand million (1,000,000,000) for several decades.^[4]

The term milliard can also be used to refer to 1,000,000,000; whereas «milliard» is rarely used in English,^[5] variations on this name often appear in other languages.

In the South Asian numbering system, it is known as 100 crore or 1 arab.

1,000,000,000 is also the cube of 1000.

Sense of scale[edit]

The facts below give a sense of how large 1,000,000,000 (10⁹) is in the context of time according to current scientific evidence:

Time[edit]

• 10⁹ seconds (1 gigasecond) equal 11,574 days, 1 hour, 46 minutes and 40 seconds (approximately 31.7 years, or 31 years, 8 months, 8 days).
• About 10⁹ minutes ago, the Roman Empire was flourishing and Christianity was emerging. (10⁹ minutes is roughly 1,901 years.)
• About 10⁹ hours ago, modern human beings and their ancestors were living in the Stone Age (more precisely, the Middle Paleolithic). (10⁹ hours is roughly 114,080 years.)
• About 10⁹ days ago, Australopithecus, an ape-like creature related to an ancestor of modern humans, roamed the African savannas. (10⁹ days is roughly 2.738 million years.)
• About 10⁹ months ago, dinosaurs walked the Earth during the late Cretaceous. (10⁹ months is roughly 83.3 million years.)
• About 10⁹ years—a gigaannus—ago, the first multicellular eukaryotes appeared on Earth.
• About 10⁹ decades ago, galaxies began to appear in the early Universe which was then 3.772 billion years old. (10⁹ decades is exactly 10 billion years.)
• The universe is thought to be about 13.77 × 10⁹ years old.^[6]

Distance[edit]

• 10⁹ inches is 15,783 miles (25,400 km), more than halfway around the world and thus sufficient to reach any point on the globe from any other point.
• 10⁹ metres (called a gigametre) is almost three times the distance from the Earth to the Moon.
• 10⁹ kilometres (called a terametre) is over six times the distance from the Earth to the Sun.

Area[edit]

• A billion square inches could make a square about one half mile on a side.
• A bolt of finely woven 1000-TC bed sheet linen with a billion thread crossings would have an area of 40 square metres (48 sq yd), comparable to the floor area of a motel unit.

Volume[edit]

• There are one billion cubic millimetres in a cubic metre, and a billion cubic metres in a cubic kilometre.
• A billion grains of table salt or granulated sugar would occupy a volume of about 2.5 cubic feet (0.071 m³).
• A billion cubic inches would be a volume comparable to a large commercial building slightly larger than a typical supermarket.

Weight[edit]

• Any object that weighs one billion kilograms (2.2×10⁹ lb) would weigh about as much as 5,525 empty Boeing 747-400s.
• A cube of iron that weighs one billion pounds (450,000,000 kg) would be 38.62 metres (126.7 ft) on each side.

Products[edit]

• As of July 2016, Apple has sold one billion iPhones.^[7] This makes the iPhone one of the most successful product lines in history, surpassing the PlayStation and the Rubik’s Cube.
• As of January 2023, Facebook has 2.963 billion users.^[8]

Nature[edit]

• A small mountain, slightly larger than Stone Mountain in Georgia, United States, would weigh (have a mass of) a billion tons.
• There are billions of worker ants in the largest ant colony in the world,^[9] which covers almost 4,000 miles (6,400 km) of the Mediterranean coast.
• In 1804, the world population was one billion.

Count[edit]

A is a cube; B consists of 1000 cubes the size of cube A, C consists of 1000 cubes the size of cube B; and D consists of 1000 cubes the size of cube C. Thus there are 1 million A-sized cubes in C; and 1,000,000,000 A-sized cubes in D.
