Tablespoons to Cups
Sixteen tablespoons fit in one cup, but who is counting that high.
The tablespoon-to-cup conversion is one of the simplest in cooking but also one of the most frequently needed. There are 16 tablespoons in one US cup. So 4 tablespoons is a quarter cup, 8 tablespoons is half a cup, 12 tablespoons is three-quarters of a cup, and 16 tablespoons is one full cup.
This converter handles the less-common fractional amounts (7 tablespoons, 13 tablespoons) that real recipes sometimes call for. It works for any ingredient since we are converting volume-to-volume. Unlike cups-to-grams which depends on ingredient density, cups and tablespoons are both units of volume and have a fixed relationship.
One small note: US tablespoons are slightly different from Australian tablespoons (15 mL vs 20 mL), which the converter handles if you switch the region setting. Most English-language recipes use US standards by default.

The Reference
A US tablespoon is 14.79 mL (often rounded to 15 mL). 16 tablespoons make a US cup (240 mL). Australian tablespoons are 20 mL, so only 12.5 fit in a metric cup (250 mL), giving different math.
Most English-language recipes use US standards by default. When in doubt, check the recipe source country.
The Humble Tablespoon in Professional Cooking
Professional chefs rarely measure in tablespoons for main ingredients, preferring grams for precision. But tablespoons persist for small amounts: spices, extracts, oils used in small quantities. 16 tablespoons equal 1 US cup. This ratio has been standardized since the early 20th century when standardized kitchen measuring became common in American home cooking.
The tablespoon-to-cup ratio is a pure volume-to-volume conversion. Unlike our cups-to-grams converter, no ingredient density is needed. 16 tablespoons of flour equal 1 cup of flour; 16 tablespoons of water equal 1 cup of water; 16 tablespoons of honey equal 1 cup of honey.
International variations exist but are rare in English-language recipes. Most British, Canadian, and American recipes follow the 16:1 ratio. Australian recipes use a 12.5:1 ratio because the Australian tablespoon is 20 mL instead of 15 mL. Our converter handles both.

Frequently Asked Questions
How many tablespoons are in 1 cup?
16 US tablespoons equal 1 US cup. This is a volume-only conversion, so it is the same regardless of what is in the spoon.
What about Australian tablespoons?
Australian tablespoons are 20 mL, versus 15 mL for US. So a tablespoon in an Australian recipe delivers more volume. About 12.5 Australian tablespoons make a metric cup (250 mL).
Is a soup spoon the same as a tablespoon?
No. Soup spoons are typically larger and non-standard. Use a proper measuring tablespoon for any recipe that calls for a precise amount.
How precise do tablespoon measurements need to be?
For cooking, not very. A slightly rounded or scant tablespoon is usually fine. For baking (especially with leaveners like baking powder or baking soda), level measurements matter.
What is 3 tablespoons in cups?
3 tablespoons equals 3/16 of a cup, or about 0.1875 cups. There is no simple fraction. Recipes usually just say 3 tablespoons rather than converting.
