Units and exact values

All conversions go through the liter. US and UK units are defined exactly in terms of the liter or the cubic inch, so the conversion factors are exact. US and UK (imperial) units share names but are different sizes, so they are listed separately.

  • 1 US gallon = 3.785411784 liters (4 quarts, 8 pints, 16 cups, 128 fluid ounces)
  • 1 US fluid ounce = 29.5735295625 milliliters
  • 1 US cup = 236.5882365 milliliters (16 tablespoons)
  • 1 US tablespoon = 14.78676478125 milliliters (3 teaspoons)

Good to know

  • US or UK? A UK gallon is about 20% bigger than a US gallon, and a UK pint is about 20% bigger than a US pint. Check which one a recipe or label uses.
  • Cups: this tool uses the US customary cup (236.588 mL). Metric cups used in some countries are 250 mL, and the US nutrition-label cup is 240 mL, so results can differ slightly from those.
  • Fluid ounces and ounces: a fluid ounce measures volume, not weight. This tool does not convert between volume and weight, because that depends on the ingredient.
  • Rounding: results are shown to about 10 significant digits. Very large and very small results appear in scientific notation, such as 1.5e-9.
  • Numbers: you can type commas, such as 1,250, and negative numbers are allowed.
