The two units
- US tablespoon (tbsp)
- Three teaspoons, about 14.79 ml. Australia is the outlier at four teaspoons to the tablespoon.
- 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.
