A short history of volume units

Volume units split into two main families: metric (litre, derived from the cubic decimetre) and imperial (gallon, quart, pint, fluid ounce). The litre was defined in 1795 alongside the metre. The US gallon (231 cubic inches, 3.785 L) and the imperial gallon (4.546 L) diverged after the UK redefined its gallon in 1824, which is why an American pint is 473 mL and a British pint is 568 mL.

Common mistakes when converting volume

US vs imperial gallon

A US gallon is about 16% smaller than an imperial gallon. A car rated 30 US mpg is roughly 36 imperial mpg.

Fluid ounce vs ounce

A fluid ounce is a volume; an ounce is a weight. They are different quantities and only match for water at specific conditions.

Confusing cubic centimetre with millilitre rules of thumb

1 cm³ equals 1 mL exactly — this is by definition, not approximation.
