Where this conversion shows up
Drink cans, cocktail recipes, cosmetics and airport security all speak fluid ounces. The famous TSA carry-on rule — 3.4 fl oz — is just 100 mL rounded. Note the US fluid ounce (29.57 mL) differs slightly from the imperial one (28.41 mL) in old British recipes.
Worked example
A cocktail recipe specifies 2 fl oz of spirits: 2 × 29.5735 = 59.1 mL — almost exactly a European 60 mL double. A 12 fl oz soda can is 355 mL.
Rounding and precision
Bartenders round to 5 mL steps and lose nothing. Cosmetics and travel limits are where precision matters: 3.4 fl oz = 100.55 mL, so a "100 mL" bottle is legal but a "3.5 oz" (103.5 mL) one technically isn't.
