- A system of numeric names in which every new term greater than million is 1,000,000 times the previous term. (i.e., a billion is a million million.)
Calque of the French Ã©chelle longue.
The system used in many European countries for numbers greater than one million. In the long scale, a billion is a million millions rather than a thousand millions, which is the "short scale. Often called the British numbering system, the long scale was used in the U.K. until the mid-1970s, and numbers in older British documents are in long scale. See space/time and binary values. Short Scale (U.S.) One billion 1,000,000,000 One trillion 1,000,000,000,000 Long Scale (Europe) One billion 1,000,000,000,000 One trillion 1,000,000,000,000,000,000
