Need to convert Fluid Ounces to US Pints (fl oz → pt)? The converter above delivers instant results. Below: the exact conversion factor, a reference table, real-world examples, and the history of both units — everything you need for accurate fl oz to pt conversion.
The History of the Fluid Ounce
The fluid ounce (29.57 mL in the US; 28.41 mL in the UK) measures volume, not mass — distinct from the weight ounce. A standard US soda can holds 12 fl oz (355 mL); a shot glass is 1.5 fl oz (44 mL); an espresso is 1 fl oz (30 mL). The fluid ounce appeared in the 14th century as one-eighth of a fluid cup, itself one-eighth of a gallon. The US and UK fluid ounces diverged after 1824 when Britain redefined its liquid measures.
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.
