mL to fl oz and fl oz to mL Converter

millilitres to US fluid ounces formula

fl oz = mL ÷ 29.5735295625

1 millilitre = 0.0338140226 US fluid ounces, so multiply millilitres by 0.0338140226. Going the other way, 1 US fluid ounce = 29.57352961 millilitres.

How the ML To Fl Oz works

Ml to fl oz: the factor

A US gallon is 128 fluid ounces and exactly 3,785.411784 mL, so a fluid ounce is 29.5735295625 mL and a millilitre is 1 ÷ 29.5735 = 0.03381402 fl oz. For kitchen work, 30 mL to the ounce is within 1.5% and easy to use: divide millilitres by 30.

US and imperial fluid ounces

The imperial fluid ounce is 28.4130625 mL, 4% smaller than the US one, and there are 20 of them in an imperial pint against 16 US fl oz in a US pint. So 500 mL is 16.9 US fl oz but 17.6 imperial fl oz. Modern British recipes are metric; older ones and Australian ones written in ounces mean imperial. American nutrition labels use a rounded "US food labelling" ounce of exactly 30 mL, which is why a 355 mL can says 12 fl oz rather than 12.005.

Worked example: a 750 mL wine bottle

750 × 0.033814 = 25.36 fl oz. That is why the standard bottle is described as "25.4 oz" on American shelves, and why a 5 oz pour gives five glasses. A 330 mL can is 11.16 fl oz; the American 12 oz can is 355 mL. A 500 mL bottle of water is 16.9 fl oz, the "16.9 oz" printed on the label.

Worked example: a recipe calling for 120 mL of milk

120 × 0.033814 = 4.06 fl oz, which an American recipe would write as ½ cup. A US cup is 8 fl oz, 236.6 mL, though recipe writers use 240 mL. A tablespoon is 14.79 mL, usually rounded to 15, and a teaspoon 4.93 mL, rounded to 5. So 15 mL is 0.51 fl oz and the 5 mL teaspoon is a sixth of an ounce.

Fluid ounces are not ounces

A fluid ounce measures volume; an ounce measures weight. They match for water — 1 fl oz of water weighs 1.04 oz — but not for anything else. 100 mL of honey is 3.38 fl oz and weighs 5 oz; 100 mL of flour is 3.38 fl oz and weighs about 2 oz. Convert a weight in grams to ounces on the grams-to-ounces page, not here.

Worked example: the 3.4 oz airline limit

3.4 × 29.5735 = 100.55 mL. The cabin-baggage liquid limit is 100 mL almost everywhere, and American packaging labels the same bottles 3.4 fl oz. A 3 oz bottle is 88.7 mL, safely inside the limit; a 4 oz bottle is 118 mL and will be confiscated.

Worked example: 8 fl oz in a recipe

8 × 29.5735 = 236.6 mL, one US cup. Recipe writers round the cup to 240 mL, so ½ cup is 120 mL and ¼ cup is 60 mL. A 12 oz can is 355 mL; a 16 oz pint glass is 473 mL; a 2-litre bottle is 67.6 fl oz. If a recipe gives ounces for a dry ingredient such as flour, it means weight — use the ounces-to-grams page.
