To convert tablespoons to cups (tbsp to cup), multiply by 0.0625. 1 tablespoon equals 0.0625 cup, about 3 times as much as a teaspoon.
| tablespoons | cups |
|---|---|
| 1 tablespoon | 0.0625 cup |
| 2 tablespoons | 0.125 cup |
| 5 tablespoons | 0.3125 cup |
| 10 tablespoons | 0.625 cup |
| 25 tablespoons | 1.5625 cup |
| 50 tablespoons | 3.125 cup |
| 100 tablespoons | 6.25 cup |
| 250 tablespoons | 15.625 cup |
| 500 tablespoons | 31.25 cup |
| 1000 tablespoons | 62.5 cup |
The factor is exactly 0.0625. It is a terminating decimal, so nothing on this page is rounded.
No simple round multiplier is close enough to be useful, so this is one to look up rather than estimate. Use the exact factor of 0.0625 when it matters.
Going the other way, one cup is 16 tbsp, which is usually the easier direction to work in. Because the forward factor is small, watch the decimal place rather than the digits: a factor-of-ten slip is the common error, not a rounding one.
To anchor the scale: 20 tablespoons is about 1.25 cup.
