Convert Tablespoon to Cup (tbsp → cup)

Converting tablespoons to cups is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in tablespoons

   Start with the number of tablespoons (tbsp) you want to convert.
2. 2
   Multiply by 0.061667

   The conversion factor from tbsp to cup is 0.061667. Multiply your value by this number.
3. 3
   Read the result in cups

   The result is your value in cups (cup).

Multiply the value in tablespoons by 0.061667. For the reverse direction, multiply by 16.216216.

• ✓US tbsp = 15 ml (practical); 14.787 ml (legal); 3 teaspoons in any system.
• ✓Australian tablespoon = 20 ml — 33% larger. Adjust when using Australian recipes.
• ✓For accurate cooking, weigh dry ingredients rather than measuring by tablespoon.

• ✗Using an Australian tablespoon (20 ml) for a US recipe (15 ml) — 33% overshoot.
• ✗Treating teaspoon and tablespoon as interchangeable — tablespoon is 3× larger.
• ✗Using a dinner spoon from the cutlery drawer as a tablespoon — they vary widely.

What is the Tablespoon?

The tablespoon equals exactly 15 milliliters (international culinary standard) or about 14.787 mL (US strict definition based on ½ fluid ounce). The tablespoon is a near-universal cooking measure for ingredients larger than a teaspoon but smaller than a cup — typical uses include oils, sauces, and condiments. The Australian tablespoon is uniquely 20 mL (4 teaspoons rather than 3), an oddity in international recipe interpretation. Standard recipes assume 1 tbsp = 15 mL globally except in Australia and the United States (where it is sometimes 14.787 mL but commonly rounded to 15 mL). The tablespoon relates to the teaspoon (3 tsp = 1 tbsp), the cup (16 tbsp = 1 cup), the fluid ounce (2 tbsp = 1 US fl oz), and the milliliter (1 tbsp = 15 mL conventional). Measuring spoons are calibrated to the local convention.

What is the Cup?

The US cup equals exactly 240 milliliters (a definition standardized for nutrition labeling; the legal volume for cooking is 236.588 mL, derived from 8 US fluid ounces). The cup is the cornerstone of American baking and home cooking, with virtually every US recipe using volume measurements rather than the weight measurements common in European cooking. Standard measuring-cup sets include 1, ½, ⅓, and ¼ cup sizes. The metric cup (used in Australia, New Zealand, and increasingly in international recipes) is exactly 250 mL — slightly larger than the US cup. The cup relates to the gallon (16 cups = 1 gal), the pint (2 cups = 1 pt), the fluid ounce (8 fl oz = 1 cup), the tablespoon (16 tbsp = 1 cup), and the milliliter (1 cup ≈ 237–240 mL). American baking-by-volume is sometimes criticized internationally for its variability compared to gram-based measurements.
