Products sold worldwide are usually filled to round metric volumes and labeled in ounces for the US market, which is why ounce figures such as 16.9 and 25.4 look odd. The milliliter number is the one the factory worked to; the ounce number is the conversion.
When you portion a drink or a sauce, it is often easier to stay in milliliters. A measuring jug with a metric scale is accurate to a few milliliters, while ounce marks on the same jug usually step by a full ounce, nearly 30 mL.
Cabin bag liquid limits
Airport security rules in many countries cap each liquid container in carry-on luggage at 100 mL, shown in the US as 3.4 oz. The rule is about the size of the container, not how full it is, so a half-empty 200 mL bottle still fails. Check the current rules of the airport you leave from, since screening technology has started to change them in some places.
UK fluid ounces are smaller
One UK fluid ounce is 28.4130625 mL, about 4% less than the US ounce. A 500 mL bottle is 16.9 US fl oz but 17.6 UK fl oz, so make sure a recipe or a label means the US unit.
- 1 L = 33.81 US fl oz
- 1 L = 35.20 UK fl oz
