Liquid Measurement (US Customary System):
- 16 oz = 1 pint; 2 pints = 1 quart; 4 quarts = 1 gallon
Liquid Measurement (Metric System):
- 1 Liter = 1 quart + 2 oz
- 1 Liter = 1000 mL
Abbreviations: oz = ounces, L = liter, mL = milliliter
Units for smaller volumes:
- 1 Tablespoon = 1/2 oz
- 1 teaspoon = 1/6 oz
Can you show why: 3 teaspoons = 1 Tablespoon?
Note: in the US Customary (Standard) System of measurement, ounces are used twice.
- They are used to refer to capacity (volume, 3D) measurements and are sometimes called liquid ounces. 16 oz = 1 pint
- They are used to refer to weight. 16 oz = 1 pound
And just to make it fun, 1 oz of liquid water does weigh about 1 oz.
