To convert cups to tablespoons (cup to tbsp), multiply by 16. 1 cup equals 16 tbsp, about 67% of a soft-drink can.
| cups | tablespoons |
|---|---|
| 1 cup | 16 tbsp |
| 2 cups | 32 tbsp |
| 5 cups | 80 tbsp |
| 10 cups | 160 tbsp |
| 25 cups | 400 tbsp |
| 50 cups | 800 tbsp |
| 100 cups | 1,600 tbsp |
| 250 cups | 4,000 tbsp |
| 500 cups | 8,000 tbsp |
| 1000 cups | 16,000 tbsp |
The factor is exactly 16. It is a terminating decimal, so nothing on this page is rounded.
For mental arithmetic the factor is close enough to 16 to use directly: multiply cups by 16 and the answer is right to within a rounding error.
The reverse factor is 0.063, so one tablespoon is that many cups. Two decimal places is plenty for most purposes, and three is more than a tape measure can justify.
To anchor the scale: 1 cup is about 16 tbsp.
