Tbsp to Cups

Convert tablespoons to cups using standard volume conversion ratios.

What this tool does

Convert tablespoons to cups using standard volume conversion ratios. Type an amount in US tablespoons, choose the units, and the tool converts it to US customary cups. It offers 5 volume units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one: US tablespoon, US customary cup, US teaspoon, Milliliter, US fluid ounce. Starts as US tablespoon.
  • To: Choose one of the same 5 units as "From". Starts as US customary cup.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from US tablespoons to US customary cups:

  • 1 tbsp (US) = 0.0625 cup (US)
  • 5 tbsp (US) = 0.3125 cup (US)
  • 10 tbsp (US) = 0.625 cup (US)
  • 50 tbsp (US) = 3.125 cup (US)
  • 100 tbsp (US) = 6.25 cup (US)

Multiply the number of US tablespoons by 0.0625 to get US customary cups. Both units are exact definitions, so 0.0625 is the exact factor: 1 tbsp (US) = 0.0625 cup (US).

Sources: US tablespoon: exact by definition. US customary cup: exact by definition.

Limitations

  • Converts the unit of a volume only. It does not work out a volume from dimensions or weight.
  • Sizes of cups, spoons, gallons and barrels differ between countries. Check that the unit chosen matches your recipe or source.
