Short and long scale usage throughout the world

Depending on the nations, various ways are used to form the names of big numbers: the long numeric scale and the short numeric scale.

In the long scale, every new word greater than a million is one million times bigger than the previous term (the digits are grouped by 6). In the short scale, every new word greater than a million is one thousand times bigger than the previous term (the digits are grouped by 3).

Long scale:
1,000,000,000 = One billion;
1,000,000,000,000 = One trillion; 1,000,000,000,000,000 = One billiard; 1,000,000,000,000,000,000 = One trillion.

Short Scale:
1,000,000,000 = One milliard;
1,000,000,000,000 = One billion; 1,000,000,000,000,000 = One quadrillion; 1,000,000,000,000,000,000 = One quintillion.
