How to convert ml to fl oz
Example: a 330 ml soda can is 330 ÷ 29.57 = 11.16 fl oz — why European cans feel slightly smaller than the US 12 oz (355 ml) standard. Mental math: divide by 30 (about 1.4% low). Note these are fluid ounces — volume, not weight.

Sizes you'll recognize
- Travel liquids: the security limit of 100 ml is 3.38 fl oz — the reason US toiletries say "3.4 oz".
- Kitchen: 1 US cup is 236.6 ml (8 fl oz); a teaspoon is 4.9 ml, a tablespoon 14.8 — recipe writers round to 5 and 15.
- Drinks: a shot is 44 ml (1.5 oz) in the US; wine pours 148 ml (5 oz); a UK pint is 568 ml (19.2 US fl oz), out-sizing the US pint's 473 ml.
- Baby bottles: commonly marked both ways — 120 ml is 4.1 oz, 240 ml is 8.1 oz.
US vs imperial fluid ounces
The US fluid ounce is 29.574 ml; the older imperial (UK) fluid ounce is 28.413 ml — 4% smaller. This converter uses US fl oz, the standard on product labels worldwide. For weight ounces (28.35 g), you want a kitchen scale, not this page: 100 ml of honey weighs far more than 100 ml of flour.
Frequently asked questions
How many ounces is 100 ml?
3.38 US fl oz — the airport carry-on limit, which is why travel bottles are labeled 3.4 oz. Ten of those fit the typical one-litre security bag almost exactly.
How many ounces is 500 ml?
16.9 US fl oz — the standard half-litre water bottle, sold in the US as '16.9 FL OZ'. A full litre is 33.8 oz.
Is 1 oz exactly 30 ml?
No — it's 29.5735 ml, but the 30 ml approximation is universal in cooking and medicine dosing cups, off by only 1.4%.
Are fluid ounces the same as weight ounces?
No. Fluid ounces measure volume; avoirdupois ounces measure weight (28.35 g). They coincide only for water-like liquids: 8 fl oz of water weighs about 8.3 oz. For dense liquids like honey the gap is huge.
How many ml in a cup?
A US legal cup is 240 ml (nutrition labels), a US customary cup 236.6 ml, and a metric cup 250 ml. Recipes rarely care about the difference; chemistry does.
