Cups, Fluid Ounces, Pints, and Quarts (US)
US kitchen and container measures form a ladder from the teaspoon to the gallon, and most steps are simple doublings. This guide lays out the US ladder in milliliters and explains why “a cup” can mean three different amounts.

Three different cups
- The US customary cup of 8 US fluid ounces is 236.5882365 mL. This is the cup the Volume Converter uses.
- US nutrition labels round a cup to 240 mL.
- Some countries, such as Australia, use a 250 mL metric cup.
Imperial pints are bigger
A UK imperial pint is 20 imperial fluid ounces, or 568.26125 mL — about 20% more than a US pint of 473.176473 mL. A pint of beer in the UK is an imperial pint.
Fluid ounces measure volume
Fluid ounces measure how much space something takes up, not how heavy it is. A cup of flour and a cup of water fill the same cup but weigh very different amounts.
