How do you convert fluid ounces to milliliters?
Multiply the number of US fluid ounces by 29.57. For speed, count 30 ml per ounce: the gap is 1.4 %, invisible in a glass, awkward in a baby bottle.
milliliters = US fluid ounces × 29.5735US fluid ounces = milliliters ÷ 29.5735
Where these two units are used
The US fluid ounce is one hundred and twenty-eighth of a gallon, that is 29.5735 milliliters, and turns out larger than the imperial one of 28.4131 even though its gallon is smaller. The milliliter equals the cubic centimeter exactly, and it is the unit of syrup doses, syringes and cosmetic bottles.

The US fluid ounce is exactly 29.5735295625 ml, defined as 1/128 of a US gallon. The imperial fluid ounce is 28.4130625 ml, or 1/160 of an imperial gallon. Methodology & sources.
Frequently asked questions
US or imperial fluid ounce?
The US one is 29.57 ml, the imperial 28.41 ml, some 4 % less. American recipes and drinks use the first; in the UK labels have been in milliliters for years, and the fluid ounce survives mainly in speech.
Is a fluid ounce the same as an ounce of weight?
No, and that is the trap. The ounce of weight is 28.35 grams, the fluid ounce 29.57 milliliters. The numbers look alike but measure different quantities; they only roughly coincide for water.
How many milliliters is a US can?
12 fl oz, which is 354.9 ml, usually rounded to 355 ml on the label. The standard European can is 330 ml, slightly less; the 500 ml version corresponds to 16.9 fl oz.
Why does a US label say 240 ml for 8 fl oz?
Because American nutrition labelling counts the fluid ounce as a round 30 ml. The reference serving for drinks is set at 240 ml and printed as 8 fl oz, while eight exact ounces come to 236.6 ml. The 1.4 % gap is written into the rules, not a misprint.
Where does the gap between the US and imperial ounce come from?
From two unrelated gallons. The US gallon carries on the wine gallon of 1707, defined as 231 cubic inches. The imperial gallon of 1824 is the volume of ten pounds of water, so an imperial fluid ounce of water weighs almost exactly one avoirdupois ounce: 28.41 ml against 28.35 g. The coincidence between volume and weight only works with the British ounce.
