The two units
- US fluid ounce (fl oz)
- Exactly one 128th of a US gallon, which makes it 29.5735295625 ml exactly. The imperial fluid ounce is a different unit at exactly 28.4130625 ml, so a UK recipe calling for 10 fl oz means 284 ml and a US one means 296 ml. It is also a volume, not a weight: an ounce of flour is not a fluid ounce of flour.
- US quart (qt)
- Two pints, about 946 ml, and close enough to a litre that recipes swap them.
