Worked examples
A 100 ml travel bottle
100 ml ÷ 29.57352956 = 3.3814 fl oz (US)
100 millilitres = 3.3814 US fluid ounces. Just under 3.4 US fl oz, which is why the US security limit is written as 3.4 oz and the UK and EU limit as 100 ml.
A 330 ml can of soft drink
330 ml ÷ 29.57352956 = 11.1586 fl oz (US)
330 millilitres = 11.1586 US fluid ounces. About 11.2 fl oz. The standard US can is 12 fl oz (355 ml), so a European can holds roughly 7% less.
Converting millilitres to US fluid ounces in real life
Labels on drinks, cosmetics, baby bottles and medicine list millilitres in most countries and fluid ounces in the US, so you meet this conversion when shopping online, packing for a flight or following an American recipe. The best-known case is airport security: the 100 ml limit for liquids in hand luggage is shown as 3.4 oz in the US, because 100 ml is 3.38 US fl oz.
Watch out for two traps. First, a fluid ounce measures volume, while a plain "oz" on food packets usually means weight; for that, use grams to ounces. Second, the UK fluid ounce is 28.41 ml, about 4% smaller than the US one, so older British recipes give slightly different numbers. The volume converter lists both.
