1/3 cup can be made using common kitchen measures like tablespoons, teaspoons, or smaller cup fractions, so you have several options if you don’t have a 1/3 cup measure on hand.

Basic equivalents

  • 1/3 cup = 5 tablespoons + 1 teaspoon.
  • In metric, 1/3 cup is about 79 milliliters (often rounded from 78.86 mL).
  • In US fluid ounces, 1/3 cup ≈ 2.66–2.67 fl oz.

Using spoons only

If you just have measuring spoons:

  • Measure out 5 level tablespoons.
  • Then add 1 level teaspoon.

Together, that gives you a very accurate 1/3 cup for both cooking and baking.

Using other cup sizes

If you have some cup measures but not 1/3:

  • 1/4 cup + 1 tablespoon + 1 teaspoon ≈ 1/3 cup.
  • Rough “close enough” approach: 1/4 cup + about 1 tablespoon if the recipe isn’t very sensitive (like many simple cooking dishes).
