For US customary cooking measures, one cup equals 16 tablespoons. The arithmetic is straightforward, but the type of cup matters. A recipe using metric or another country’s measures may use different units, so identify the recipe’s system before converting a whole ingredient list.
One US customary cup is 16 US tablespoons. Half a cup is 8 tablespoons, one quarter is 4, and one third is 5 tablespoons plus 1 teaspoon.
Go straight to the stepsBefore you begin
These are US customary volume conversions. They do not tell you how many grams an ingredient weighs, and ordinary eating spoons are not reliable measuring tools.
What you’ll need
- The recipe and its measurement system
- Actual measuring spoons or cups
Let’s do this
Step by step
- 01
Check the recipe’s units
Look for a note about US, metric, or another measurement convention. If the recipe already gives grams or milliliters, using those directly can avoid an unnecessary conversion.
- 02
Convert cups to tablespoons
Multiply the number of US cups by 16. For example, three quarters of a cup is 0.75 × 16, which equals 12 tablespoons.
- 03
Handle a partial tablespoon
A US tablespoon contains 3 teaspoons. One third of a cup is 5 tablespoons plus 1 teaspoon, not simply 5 tablespoons.
- 04
Measure consistently
Use level measures unless the recipe specifically says otherwise. For flour, spoon and level rather than packing; for liquids, use the correct marked volume.
- 05
Write down the converted amount
When scaling several ingredients, record each calculation before you begin. Tick ingredients off as you add them so repeated spoonfuls do not become a counting problem.

Volume and weight answer different questions
A cup of flour and a cup of honey occupy the same nominal volume but do not weigh the same. You cannot convert cups to grams using one universal multiplier. Use the ingredient weight supplied by the recipe or a suitable ingredient-specific chart.
For a small recipe adjustment, spoons are convenient. For a large batch, weighing a recipe’s specified gram amount is usually easier than counting many spoonfuls. Choose the method that lets you keep track reliably.
US cup-to-tablespoon quick reference
| US cups | US tablespoons |
|---|---|
| 1/4 cup | 4 tablespoons |
| 1/3 cup | 5 tablespoons + 1 teaspoon |
| 1/2 cup | 8 tablespoons |
| 2/3 cup | 10 tablespoons + 2 teaspoons |
| 3/4 cup | 12 tablespoons |
| 1 cup | 16 tablespoons |
A quick final check
- The recipe uses the same measurement system.
- The conversion is written down.
- The tool is a measuring spoon, not cutlery.
Common questions & sticking points
How many tablespoons are in half a cup?
Eight US tablespoons equal half a US customary cup.
Does this table apply to every country’s cups?
No. Cup and tablespoon conventions can differ. Use the recipe’s stated units and do not mix systems.
How many teaspoons are in a tablespoon?
Three US teaspoons equal one US tablespoon. Use measuring spoons, and keep the same measurement system throughout the recipe.
