Metric Prefixes

Metric Prefixes are generally understood to include both the long scale and the short scale.

Why both are used still is as easily explained as saying... 'Britain' and 'France'.

In the English speaking world the short scale is mostly used while Europe and the rest of the world use the long scale.

What are the differences you ask?

Well, the short scale Billion prefix (109) is giga, Trillion prefix (1012) is tera, Billionth prefix (10-9) is nano, Trillionth prefix (10-12) is pico and so on.

The long scale for metric prefixes is the more widely known and consists of Billion prefix (1012) is tera, Trillion prefix (1018) is eksa, Billionth prefix (10-12) is pico and so on..

The International Bureau of Weights and Measures (also known by its French name: Bureau International des Poids et Mesures, or BIPM) maintains and implements standards of units and measurements around the world including metric prefixes. The SI (Systeme International d’Unites) or International System of Units is the direct result of their formation and subsequent meetings from their inception in 1875.
