Millilitres to Fluid Ounces

This page converts to US fluid ounces, at 29.5735 millilitres each.

That qualifier is the whole point. An imperial fluid ounce is 28.4131 millilitres — about 4% smaller — and the difference compounds badly at larger volumes: a US pint is 473ml and an imperial pint is 568ml, a gap of 20%. Any converter that offers "fluid ounces" without saying which one is guessing on your behalf.

Use the US ounce for American recipes and product labels. Use the imperial one for British recipes and anything sold by the pint in the UK. The hub converter has both.

The formula

fluid ounces (us) = millilitres ÷ 29.5735296
