Where the fluid ounce to milliliter factor comes from
- One US fluid ounce is 1/128 of a US gallon, which is exactly 29.5735295625 millilitres.
- That constant is the conversion directly.
- millilitres = US fl oz × 29.5735295625. So 8 fl oz is 236.59 ml and 16 fl oz is 473.18 ml.
- An imperial (UK) fluid ounce is smaller, 28.4130625 ml, so 8 imperial fl oz is 227.30 ml instead.

Common mistakes
A US cup is 8 fl oz, but a metric cup is 250 ml
8 US fl oz is 236.59 ml, the size of a US cup. Many metric recipes use a 250 ml cup, which is 8.45 US fl oz. The 13 ml difference is enough to matter in baking, so check whether 'a cup' means US customary or metric.
Imperial fluid ounces make a bigger pint
A US pint is 16 fl oz (473 ml); a UK pint is 20 imperial fl oz (568 ml). The UK pint is larger even though its ounce is smaller, because it contains more of them. So '1 pint' is not a fixed volume across countries.
To convert fluid ounces to milliliters, multiply the number of fluid ounces by 29.5735. One fluid ounce equals 29.5735 milliliters, and one milliliter equals 0.033814 fluid ounces, so the relationship is fixed and exact. As a worked example, 10 fl oz comes to 295.74 ml.
