pro tips
Rough math: divide by 34. A 12 fl oz can is about 0.35 litres.
8 fl oz is 237 ml, a US cup — the one nice overlap.
A 20 fl oz bottle is 0.59 litres, which is more than half a litre of "medium".
what it does
One US fluid ounce is 0.0296 liters. Divide fluid ounces by 33.81 and the liters appear, which is what a US recipe needs when the jug is metric.
It shows up when a bottle measured in fluid ounces has to be described in litres for a metric market, when a recipe in fluid ounces meets a metric jug, when travel-size limits are checked in millilitres against ounce-marked containers, and in any kitchen where the two systems share a shelf.
The shortcut: 34 fl oz is about 1 litre, 17 fl oz is 0.5, and 8 fl oz is about 237 ml — a cup. The US fluid ounce is 29.57 ml, so a fluid-ounce recipe translates into slightly ugly millilitres, which is why nobody converts more than once.
