Recipes are inconsistent about this — some list ingredients in tablespoons, others in cups, and scaling a recipe up or down often means converting between the two on the fly. Since a tablespoon and a cup are both units of volume, this conversion is a fixed ratio, unlike a gram-to-cup conversion which changes with every ingredient.
Tablespoons to cups quick reference
| Cup measurement | Tablespoons |
|---|---|
| 1/8 cup | 2 tbsp |
| 1/4 cup | 4 tbsp |
| 1/3 cup | 5 tbsp + 1 tsp |
| 1/2 cup | 8 tbsp |
| 2/3 cup | 10 tbsp + 2 tsp |
| 3/4 cup | 12 tbsp |
| 1 cup | 16 tbsp |
| 1 1/2 cups | 24 tbsp |
| 2 cups | 32 tbsp |
How to convert tablespoons to cups
Since there are always 16 tablespoons in 1 US cup, the formula is fixed regardless of what you're measuring.
| Example | Result |
|---|---|
| 8 tbsp ÷ 16 | 0.5 cups |
| 24 tbsp ÷ 16 | 1.5 cups |
| 5 tbsp ÷ 16 | ≈ 0.31 cups |
To go the other way, multiply cups by 16. Going from 1/3 cup gives 16 × 0.333 = 5.33 tablespoons, which is why it's usually written as "5 tablespoons plus 1 teaspoon" instead of a decimal.
Why this conversion is fixed, unlike grams
Tablespoons and cups are both units of volume, so the relationship between them never changes — 16 tablespoons always equals 1 cup, whether you're measuring flour, sugar, water, or oil. This is different from a grams-to-tablespoons conversion, which depends entirely on the ingredient's density. That's what makes this particular converter simple: no ingredient selector needed.
1 tablespoon
= 3 teaspoons, or 1/16 of a cup.
1/3 cup
The trickiest one — 5 tbsp + 1 tsp, since 16 doesn't divide evenly by 3.
Liquid vs dry
The 16 tbsp = 1 cup ratio holds for both — it's a volume rule, not ingredient-specific.
Level vs heaped
Always use level tablespoons unless a recipe specifically says "heaped."
How to use this converter
Type a value into either the tablespoons or cups field, and the other field updates instantly with the converted amount. This works the same way for both liquid and dry ingredient measurements in standard US cooking measurements.
When you'll need this conversion
- Scaling a recipe up or down and needing to convert the new tablespoon amounts into cups for easier measuring.
- Following an older recipe that lists small quantities in tablespoons rather than fractional cups.
- Doubling or halving a recipe where the tablespoon amount no longer divides into a clean fraction.
Frequently asked questions
How many tablespoons are in 1/3 cup?
There are approximately 5 tablespoons plus 1 teaspoon in 1/3 cup, since 1 cup equals 16 tablespoons and 16 doesn't divide evenly by 3.
How many tablespoons are in 1/4 cup?
There are exactly 4 tablespoons in 1/4 cup.
How many tablespoons are in a full cup?
There are 16 tablespoons in one full US cup.
How many tablespoons are in 1/2 cup?
There are 8 tablespoons in 1/2 cup.
How many tablespoons are in 2/3 cup?
2/3 cup is 10 tablespoons plus 2 teaspoons, since it's double the amount in 1/3 cup.
Is this the same for liquid and dry ingredients?
Yes. Tablespoons and cups are both units of volume, so the ratio of 16 tablespoons per cup holds for both liquid and dry ingredients, unlike a gram conversion which changes by ingredient density.
How many teaspoons are in a tablespoon?
There are 3 teaspoons in 1 tablespoon, which is why odd amounts like 1/3 cup are written as tablespoons plus teaspoons rather than a fraction of a tablespoon.
