US vs. UK (Imperial) Gallons, Quarts & Pints
A US gallon and a UK (Imperial) gallon aren't the same size — the UK gallon is about 20% larger, at 4.546 liters versus 3.785 liters for the US gallon. That gap carries through to quarts and pints too, since they're just fixed fractions of a gallon in both systems. This trips people up most often with fuel economy (miles per gallon means something different in the US vs the UK) and with older British recipes or product measurements.
