About these units

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).

Baker's Dozen (13)

Medieval EnglishTraditional unit (still used in some regions)

Thirteen items. Traditionally explained as medieval English bakers adding a thirteenth loaf to each dozen; the tie to bread-weight laws is plausible but unproven.

A baker's dozen is thirteen, one more than the twelve a customer asked for. The usual explanation is that medieval English bakers added an extra loaf to stay out of trouble under the Assize of Bread and Ale, which tied the price of bread to the price of wheat. Henry III revived the law in 1266, and bakers who sold short weight could be fined, pilloried, or flogged. The extra bread is traditionally called the vantage loaf or the in-bread.

How well attested is the story? The Assize and its penalties are well documented, and the early 15th-century London book Liber Albus describes an old custom of giving retailers 13 loaves for the price of 12, which one historian reads as a resale margin rather than a safeguard. The phrase itself is recorded only from the late 1500s, with Thomas Nashe in 1596, and no surviving record links it directly to the law. The Assize regulated weight, not count, so the tidy explanation has gaps. Reference sources differ in how firmly they accept the link, but none cites direct proof.

1 baker's dozen = 13 pieces (exactly).
