大 きさの感覚
[時間
[十 億 秒 は11,574日 1時 間 46分 40秒 である。(約 31.7年 。)十 億 分 (およそ1901年 )前 は、ロ ーマ帝国 が繁栄 し、キリスト教 が発展 していた。- 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]
距離
[- 109 inches is 15,783マイル (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.
面積
[- 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
平方 メートル (48 sq yd), comparable to the floor area of a motel unit.
体積
[- 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
立方 フィート (0.071 m3). - A billion cubic inches would be a volume comparable to a large commercial building slightly larger than a typical supermarket.
質量
[- Any object that weighs one billionキログラム (2.2×109 lb) would weigh about as much as 5,525 empty Boeing 747-400s.
- A cube of iron that weighs one billionポンド (450,000,000 kg) would be 38.62メートル (126.7 ft) on each side.
製品
[- 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 July 2016, Facebook has 1.71 billion users.[8]
自然
[- 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マイル (6,400 km) of the Mediterranean coast.
- In 1804, the world population was one billion.
計算
[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.
