Convert US Gallons to Pints

About converting US Gallons to Pints

US Gallons (gal (US)) and Pints (pt) are both units of volume, so converting between them is a single multiplication: multiply your US Gallons figure by 8. Ten US Gallons comes to 80 Pints, and a hundred works out at 800 Pints.

Rule of thumb: going from US Gallons to Pints multiplies, so the figure always grows — one US Gallon is already 8 Pints. If your answer came out smaller, you have the conversion the wrong way round.

What is an US Gallon?

The US gallon is defined as exactly 231 cubic inches, a figure inherited unchanged from the old English wine gallon. When Britain overhauled its measures in 1824 and adopted a new imperial gallon, the United States simply kept the wine gallon it already had — and that single decision is the root of the entire US-versus-imperial mess that still catches people out today. The US gallon is roughly a fifth smaller than the imperial one, which means American and British fuel-economy figures are not comparable even though both are quoted in miles per gallon.

What is a Pint?

The pint is where the US-imperial split becomes most visible, because both countries still use the word every day. A US pint is 16 US fluid ounces; an imperial pint is 20 imperial fluid ounces, making the British pint the larger by about a fifth. So a pint of beer in London is meaningfully more beer than a pint in New York — the same word, a different drink, and no label anywhere warns you. The imperial pint is also one of the few imperial units still legally mandated in the UK, where draught beer and cider must be sold in pints or fractions of one.

To put both in perspective: a typical American milk jug holds one US gallon, while a pint is the standard glass of beer in a British pub.
