millilitres (ml)= UK fluid ouncesThe formula
millilitres ÷ 28.4130625 = UK fluid ounces. For US fluid ounces, divide by 29.5735295625 instead.
The two fluid ounces are close enough to look interchangeable and far enough apart to spoil a recipe. A UK fluid ounce is 28.41 ml and a US fluid ounce is 29.57 ml, so a US cup of 8 fl oz is 236.6 ml while eight British fluid ounces come to 227.3 ml.
The safest approach in the kitchen is to work in millilitres wherever the recipe allows it, and to check which country a recipe came from before converting. British recipes that predate metrication usually mean imperial fluid ounces; anything written for an American audience means US fluid ounces.
