How many noughts in a milliard?

Answer 1

Milliard is a French-derived word meaning the number 1,000,000,000 = 109. That is one thousand million. The SI prefix is giga. It is not used in American English and is rare in other forms of English - the preferred term being 'thousand million'. When South Africa adopted the metric system in 1971, "milliard" was recommended by the Metrication Board, but has often been ignored in practice. During the 20th century, the short scale "billion" superseded 'thousand million' to become the normal term in most of the English-speaking world.

"Milliard", or a version thereof, is common to many languages other than English, where a "billion" often refers to a thousand "milliard" - 1,000,000,000,000.
