About the US fluid ounce and the teaspoon
The US fluid ounce
The US fluid ounce (fl oz) is a customary unit of volume equal to 1/128 of a US gallon, or about 29.5735 mL. It is the standard unit for liquid serving sizes on US nutrition labels. The US fluid ounce is slightly larger than the UK fluid ounce (28.4131 mL) — confusingly, the opposite direction from the gallons.
The teaspoon
The US teaspoon equals 1/3 of a US tablespoon, or about 4.929 mL. The metric teaspoon (used on most non-US nutrition labels) is exactly 5 mL — close enough that you can substitute freely in cooking but not in precise dosing.
