A billion (: 1000000000 ) is the Entier naturalness which follows nine hundred and ninety million nine hundred and ninety thousand and nine hundred and ninety (: 999999999) and precedes a billion one (: 1000000001).

Mathematical properties

  • :1000000000 (a billion) is a Entier naturalness.
  • 109 = 10 with the power 9

A billion is also:

  • the prefix of unit of measurement of the billion is the Giga shortened G. Thus, 1  gigawatt  = 1  GW  =: 1000000000  W  =: 1000000000  Watts.
  • In the current English language, this number is generally called a billion . What can involve a confusion with other languages whose French, because one billion means million million (or: 1,000,000,000,000 or 1×1012). The English language tolerates the " term; milliard" , but it generally is not included/understood and thus seldom not used.

In a more picturesque way:

has is a cube; B consists of: 1000 cubes of the type A. C consists of: 1000 cubes of the type B and D , of: 1000 cubes of the type C. Thus, there is 1 million cubes has in the cube C and 1 billion cubes has in Of the same cube D., for example, there is a billion cubic millimetres of water in one cubic meter of water.

Idea of the scale

The facts below gives an idea of the size of this number:
  • In connection with the flow of time:
    • There is approximately a billion minutes, the Roman Empire was flourishing. (A billion minutes is worth overall: 1900 years).
    • There is approximately a billion hours, the modern human beings (in Africa) and the néandertaliens (in Europe) lived with the Paléolithique means. (A billion hours is worth overall: 114000 years).
    • It there has approximately a billion Jour S, the Australopithèque , biped Hominidé, potential ancestor of human modern, occupied the African Savane S . (A billion days is worth overall 2,7 million years).
    • There is approximately a billion Mois, the Dinosaure S went on the Earth during the end of the Crétacé. (A billion month is worth 82 million years overall).
    • There is approximately a billion Année S, the multicellular first organizations appeared on Earth. (One currently estimates the age of the Univers at approximately 13,7 billion years).

  • In connection with the distance:

    • a billion Centimètre S is approximately the distance which separates Chicago, in the Illinois with the the United States of Tokyo to the Japan.
    • a billion inches is worth: 15783 miles, more than half of the round the world tour and sufficient to connect two point unspecified on the terrestrial sphere.
    • a billion Mètre S is almost three times the distance which separates the Ground from the the Moon.
    • a billion Kilomètre S is more than six times the distance which separates the Ground from the Sun, it is the distance covered by the light in a little more: 3000 seconds, that is to say a little less than one hour.
