Where this conversion shows up
Recipes and drinks: American recipes measure liquids in fluid ounces and cups while measuring jugs elsewhere mark millilitres. Cosmetics and travel join in — airport liquid limits are 100 ml, which Americans know as 3.4 oz, printed on every travel-size bottle in both units for exactly this reason.

Questions people ask
How many ml is 1 fluid ounce?
29.5735 ml for the US fluid ounce — 30 is the everyday rounding. The UK fluid ounce is slightly smaller at 28.41 ml; this page uses the US one that American recipes mean.
Is 100 ml the same as 3.4 oz?
Yes — 3.38 oz exactly, rounded up on packaging. That pairing is the airport liquids rule in both languages.
Are fluid ounces the same as weight ounces?
No — fluid ounces are volume, weight ounces are mass. They coincide loosely for water and diverge for everything else; grams-to-ounces handles the weight kind.
How many oz is a 750 ml bottle of wine?
25.4 oz — which is why American wine talk calls it a 'fifth': it is roughly a fifth of a US gallon.
