The History of the US Cup
The US cup (236.6 mL, exactly 8 US fluid ounces) became the de facto standard for American cooking in the 19th century when Fannie Farmer's 1896 cookbook systematized recipes using level cup measurements. The metric cup of 250 mL (used in Australia, Canada, and other countries) differs by about 5.6% — enough to affect baking outcomes when recipes aren't adapted. The distinction trips up cooks who switch between American and metric recipes.
The History of the US Pint
The US pint (473 mL) differs significantly from the UK pint (568 mL) — a 20% difference that surprises travelers. A US pint of beer is 16 fl oz; a UK pint is 20 fl oz. Strawberries, blueberries, and cherry tomatoes are sold in pint containers at US farmers' markets. The pint's definition traces to the Latin pincta ('painted'), referring to a painted line on a measuring vessel.
