About these units

Myriad (myriad)

Ancient GreekTraditional unit (still used in some regions)

Ten thousand. The word comes from Greek; in Chinese, Japanese and Korean numbers are grouped in myriads (萬/万) rather than thousands.

Greek arithmetic had a single word for ten thousand, murias, which gave English the word myriad. Its own origin is uncertain. Greek numerals wrote it with a capital mu, and Archimedes used the myriad myriad, or one hundred million, as the base of the large-number scheme in his Sand Reckoner.

English speakers now use myriad mostly to mean a vast, unspecified number, and the exact 10,000 survives mainly in translations from Greek, Latin or Chinese. Chinese, Japanese, Korean and Vietnamese still count in groups of 10,000, so that one million is expressed as one hundred wan. Other languages have a dedicated word as well, including Sanskrit ayuta, Old Turkic tumen and Hebrew revava. The prefix myria- stood for 10,000 in the original French metric system of 1795 but fell out of use, and a myriad is also a 100 kilometer grid square in British and US military mapping.

1 myriad = 10,000 pieces (exactly).

Billion (short Scale) (B)

General & non-SICurrent unit

One thousand million (10⁹). The meaning used in the US, UK and most English-speaking countries today.

For decades British and American speakers meant different things by billion. The short-scale sense, a thousand million, took hold in the United States in the 19th century, while Britain kept the older meaning of a million million. From the 1950s the short scale spread through British technical writing and journalism, and Winston Churchill had remarked in 1941 that for practical financial purposes a billion was a thousand millions.

The official break came on December 20, 1974. Asked in Parliament whether ministers would be required to use the traditional British meaning, Prime Minister Harold Wilson answered no, explaining that billion was now used internationally for 1,000 million and that using it any other way would cause confusion. He conceded it could still be read as a million million and asked colleagues to avoid ambiguity. Today a billion is 10⁹, matching the SI prefix giga, and the UN projected that world population would reach 8 billion on November 15, 2022.

1 billion (short scale) = 1,000,000,000 pieces (exactly).
