This free tablespoons to cups converter turns tablespoons into cups, with the common amounts in kitchen fractions.
It's for doubling small amounts, halving a recipe, or finding a cup you don't have.
I built it because recipes move between spoons and cups all the time, and ⅓ cup isn't a round number of tablespoons.
Here's the rule, a worked example, and a table.
TL;DRKey takeaways
What is a tablespoons to cups converter?
A tablespoons to cups converter turns a number of tablespoons into US cups.
It works for any ingredient, since both are measures of volume.
The rule
NIST Handbook 44 defines a cup as 8 fluid ounces and a tablespoon as ½ fluid ounce, so a cup holds 16 tablespoons.
| Tablespoons | Cups |
|---|---|
| 2 tbsp | ⅛ cup |
| 4 tbsp | ¼ cup |
| 5 tbsp + 1 tsp | ⅓ cup |
| 8 tbsp | ½ cup |
| 12 tbsp | ¾ cup |
| 16 tbsp | 1 cup |
A worked example
Here's the example the calculator loads: 5 tablespoons.
5 ÷ 16 = 0.3125 cups, just under ⅓ cup. Add a teaspoon to make ⅓ cup exactly.
Mistakes to avoid
These are the slips that come up most.
