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 not common anymore, and the word has been used to mean one thousand million (1,000,000,000) for several decades.https://en.oxforddictionaries.com/explore/how-many-is-a-billion https://web.archive.org/web/20170112163426/https://en.oxforddictionaries.com/explore/how-many-is-a-billion dead January 12, 2017 How many is a billion?

Sense of scale thumb|upright=1.8|Visualization of powers of ten from one to 1 billion The facts below give a sense of how large 1,000,000,000 (109) is, according to current scientific evidence: Time 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, the thin disk of the Milky Way started to form. (109 decades is exactly 10 billion years.) The universe is thought to be about 13.8 × 109 years old.http://www.esa.int/Our_Activities/Space_Science/Cosmic_detectives Cosmic Detectives 2 April 2013 European Space Agency Distance 109 inches is 15783 mi 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 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 m2 sqyd, comparable to the floor area of a motel unit. Volume 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 cuft. A billion cubic inches would be a volume comparable to a large commercial building slightly larger than a typical supermarket. Weight Any object that weighs 1000000000 kg lbs in would weigh about as much as 5,525 empty Boeing 747-400s. A cube of iron that weighs 1000000000 lbs kg in would be 38.62 m ft on each side.

In 1804, the world population was one billion. Count 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. frameless|upright=3.45 Selected 10-digit numbers (1,000,000,000–9,999,999,999) 1,000,000,000 to 1,999,999,999
