About this tool
This converter uses the standard US measurement: 1 cup equals exactly 16 tablespoons. Type a value into either field and the other updates instantly — nothing is sent to a server.
How to use it
- Type a number of tablespoons in the Tablespoons box; the Cups box fills in.
- To convert the other way, type a cup amount in Cups and read the tablespoons.
- Use decimals for part cups: 0.25 for a quarter cup, 0.5 for a half cup.
- For butter sticks, teaspoons and metric spoons, use the chart and notes further down.
Worked example
A US cup holds 16 tablespoons. Type 6 in Tablespoons and the Cups box shows 0.375 (6 ÷ 16), which is a quarter cup plus 2 tablespoons. Type 0.75 in Cups and the Tablespoons box shows 12 (0.75 × 16).

- Double-checking a measurement conversion while cooking or baking
Things to watch out for
This converter uses the US tablespoon and cup, which are standard for American recipes and US-made measuring tools — UK, Australian, and metric "cup" and "tablespoon" measurements use slightly different volumes, so a recipe from a different region may not convert perfectly using US ratios. For dry ingredients, tablespoon-to-cup conversions are by volume, not weight, so results can vary slightly depending on how tightly an ingredient like flour or brown sugar is packed.
Why this conversion trips people up
Sixteen isn't an intuitive number to multiply or divide by in your head, which is exactly why a recipe calling for "10 tablespoons" of something doesn't obviously translate to a clean fraction of a cup without doing the math. This tool handles that conversion instantly in either direction, whether you're scaling a recipe up, down, or just working with whatever measuring tool happens to be clean.

In the US system, 16 tablespoons make 1 cup.
| Tablespoons | Cups |
|---|---|
| 1 tbsp | 1/16 cup |
| 2 tbsp | 1/8 cup |
| 4 tbsp | 1/4 cup |
| 5 1/3 tbsp | 1/3 cup |
| 8 tbsp | 1/2 cup |
| 10 2/3 tbsp | 2/3 cup |
| 12 tbsp | 3/4 cup |
| 16 tbsp | 1 cup |
Butter, sticks and metric differences
One US stick of butter is 8 tablespoons, which is 1/2 cup, so a recipe calling for 4 tablespoons of butter needs half a stick. A US tablespoon is about 14.79 ml. In Australia a tablespoon is 20 ml, so 4 Australian tablespoons make 80 ml rather than the 59 ml you would get from US ones. If a recipe is from outside the US, check which tablespoon it means before you convert.
Measuring tips
Level off dry ingredients like flour and sugar with a knife rather than heaping them. For liquids, use a clear measuring cup and read it at eye level. When a recipe is small, such as 2 tablespoons of oil, it is easier and more accurate to use the tablespoon directly than to measure a fraction of a cup. See the teaspoons to tablespoons converter for smaller amounts.
Tablespoons to cups: the formula
In US measuring, 16 tablespoons make 1 cup, so cups = tablespoons ÷ 16. Each tablespoon is 3 teaspoons or half a fluid ounce, about 14.8 ml, and a US cup is 8 fluid ounces or about 236.6 ml.
| Tablespoons | Cups | Notes |
|---|---|---|
| 1 tbsp | 1/16 cup | 3 teaspoons |
| 2 tbsp | 1/8 cup | 1 fluid ounce |
| 4 tbsp | 1/4 cup | |
| 5 tbsp + 1 tsp | 1/3 cup | 5.33 tablespoons |
| 8 tbsp | 1/2 cup | One US stick of butter |
| 10 tbsp + 2 tsp | 2/3 cup | 10.67 tablespoons |
| 12 tbsp | 3/4 cup | |
| 16 tbsp | 1 cup | 8 fluid ounces |
Measuring tips
- Level dry ingredients with a knife for a true tablespoon; a heaped spoon can hold 50% more.
- Use a liquid measuring cup for liquids, and read it at eye level.
- Recipes from the UK, Australia or Canada may use different spoon sizes, so check the source country if a result looks off.

Frequently asked questions
There are exactly 16 tablespoons in 1 US cup. This is a fixed relationship in the US customary measuring system used in most American recipes.
No — a US tablespoon (14.79 mL) is slightly different from a UK/Commonwealth or Australian tablespoon (which use different standard volumes). This converter uses the US measurement, standard for American recipes and measuring spoons.
There are 3 teaspoons in 1 US tablespoon — useful if a recipe only lists teaspoon measurements and you want to convert up to tablespoons or cups.
There are 8 tablespoons in 1/2 cup, which is also one US stick of butter. A full cup is 16 tablespoons.
1/3 cup is 5 tablespoons plus 1 teaspoon, or 5.33 tablespoons. In practice it is easiest to use a 1/3 cup measure.
There are 12 tablespoons in 3/4 cup, because 3/4 of 16 is 12.
