Questions and answers
Questions about converting millilitres to fluid ounces
Is a UK fluid ounce the same as a US fluid ounce?
No, they're different sizes, a UK fluid ounce is smaller than a US one. Check which the calculator above is using before you rely on a fluid ounce figure from an American recipe.
Why is a UK pint a different size to a US pint?
The two countries never shared a single imperial system for liquid measure, so a UK pint and a US pint diverged and are now noticeably different sizes. This matters most for recipes using cups of stock or milk in pints.
Should I use fluid ounces or millilitres for a recipe?
Millilitres are less ambiguous, since there's no UK/US split to worry about. If a recipe gives fluid ounces without saying which country it's from, convert to millilitres and check the result looks sensible for the dish.
