Formula / calculation method
US cups = US tablespoons ÷ 16US tablespoons = US cups × 16Metric cups = (tablespoons × 15 mL) ÷ 250 mLAustralian metric cups = (tablespoons × 20 mL) ÷ 250 mL
Worked examples
- 4 US tablespoons equal 0.25 US cup.
- 10 US tablespoons equal 0.625 US cup.
- 128 US tablespoons equal exactly 8 US cups.
- 4 Australian tablespoons equal 0.32 of a 250 mL metric cup.
How many tablespoons are in a cup?
One US customary cup contains exactly 16 US tablespoons. For US recipes, divide tablespoons by 16 to get cups or multiply cups by 16 to get tablespoons.
- 1 US tablespoon = 1/16 cup.
- 4 US tablespoons = 1/4 cup.
- 8 US tablespoons = 1/2 cup.
- 16 US tablespoons = 1 cup.
