Where the milliliter to fluid ounce factor comes from
- This converter uses the US fluid ounce, which is 1/128 of a US gallon.
- That makes one US fluid ounce exactly 29.5735295625 millilitres.
- So one millilitre is 1 ÷ 29.5735295625 = 0.0338140227 US fluid ounces.
- US fl oz = millilitres × 0.0338140227. So 250 ml is 8.4535 US fl oz and 500 ml is 16.907 US fl oz. An imperial (UK) fluid ounce is smaller at 28.4131 ml, so 250 ml is 8.7988 imperial fl oz.

Common mistakes
US and imperial fluid ounces are not the same
A US fluid ounce is 29.57 ml; a UK (imperial) fluid ounce is 28.41 ml. Confusingly, the imperial ounce is the smaller one, so 500 ml is 16.91 US fl oz but 17.60 imperial fl oz. Recipes rarely say which they mean; assume US unless it is a British source.
Fluid ounces measure volume, ounces measure weight
A fluid ounce (fl oz) is a volume; an ounce (oz) is a mass. They match only for water and only roughly. 250 ml of honey is 8.45 fl oz of volume but weighs far more than 8.45 oz. Do not convert ml to weight ounces with this factor.
To convert milliliters to fluid ounces, divide the number of milliliters by 29.5735. One milliliter equals 0.033814 fluid ounces, and one fluid ounce equals 29.5735 milliliters, so the relationship is fixed and exact. As a worked example, 10 ml comes to 0.33814 fl oz.
