One US fluid ounce equals exactly 29.5735296 millilitres. One Imperial fluid ounce (used in the UK and some Commonwealth countries) equals 28.4130625 mL — slightly smaller. This converter shows both, with US fl oz as the primary result since most online recipes and product labels use the US measurement.

They are different units that share the same name. A US fluid ounce is 29.5735 mL, while an Imperial (UK) fluid ounce is 28.4131 mL — the Imperial ounce is about 4% smaller. The two systems also differ for cups, pints, and gallons. When following a recipe, check whether it uses US or UK measurements to avoid errors. This tool shows both side by side.

For US recipes, divide your mL value by 29.5735 to get fluid ounces. For UK recipes, divide by 28.4131. This tool does both automatically — type the mL value once, see both conversions instantly. The tool also shows cups and tablespoons for added convenience when cooking.

One US cup equals 236.5882 mL — close to 240 mL but slightly smaller. So 250 mL is approximately 1.057 US cups. The metric cup used in Australia and some other countries is 250 mL exactly, which is sometimes called a 'metric cup' to distinguish it.
