One of the most common kitchen conversions, tablespoons to cups comes up constantly in cooking and baking. Whether you're halving a recipe that calls for 1/3 cup of oil, scaling up a sauce that uses tablespoons as the measurement, or simply don't have the right measuring cup handy, knowing how to convert between these two volume units saves time and prevents recipe disasters.
In the US customary system, 1 cup = 16 tablespoons and 1 tablespoon = 3 teaspoons. A US cup is defined as exactly 236.588 milliliters, and a US tablespoon is 14.787 mL. These are different from the metric cup (250 mL) and Australian tablespoon (20 mL) used in some countries.
| Tablespoons (tbsp) | Cups | Fraction | Common Use |
|---|---|---|---|
| 1 tbsp | 0.0625 | 1/16 cup | Splash of liquid |
| 2 tbsp | 0.125 | 1/8 cup | Small serving of sauce |
| 3 tbsp | 0.1875 | 3/16 cup | 1 tbsp + 1.5 tsp |
| 4 tbsp | 0.25 | 1/4 cup | Common recipe measurement |
| 5 tbsp | 0.3125 | 5/16 cup | Butter measurement |
| 6 tbsp | 0.375 | 3/8 cup | Half of 3/4 cup |
| 8 tbsp | 0.5 | 1/2 cup | Standard stick of butter |
| 10 tbsp | 0.625 | 5/8 cup | Scaling recipes |
| 12 tbsp | 0.75 | 3/4 cup | Common baking amount |
| 14 tbsp | 0.875 | 7/8 cup | Nearly a full cup |
| 16 tbsp | 1.0 | 1 cup | Standard US cup |
| 32 tbsp | 2.0 | 2 cups (1 pint) | Pint measurement |
If your measuring cups are dirty or lost, you can use tablespoons instead. Need 1 cup of flour? Measure out 16 level tablespoons. Need 1/4 cup of sugar? That's 4 tablespoons. This works reliably for dry ingredients, though a kitchen scale is always more accurate for baking.
Halving a recipe that calls for 3/4 cup of milk? That's 12 tbsp ÷ 2 = 6 tbsp (or 3/8 cup). Doubling a recipe using 5 tbsp of oil? That's 10 tbsp (or 5/8 cup). Converting to tablespoons first makes the math simpler than working with fractions of cups.
One standard US stick of butter = 8 tablespoons = 1/2 cup = 4 ounces = 113.4 grams. If a recipe calls for "1/3 cup butter" and you only have sticks, that's 5 tbsp + 1 tsp (about 5.33 tbsp). Our converter handles these calculations instantly.
Many cold brew coffee recipes and cocktail recipes use tablespoons. A cold brew concentrate recipe calling for 12 tbsp of ground coffee translates to 3/4 cup. Cocktail recipes often use "parts" where 1 part = 2 tablespoons, making cup conversions useful for batching drinks.
Since 16 tbsp = 1 cup, divide tablespoons by 16. For easy fractions: 4 tbsp = 1/4 cup, 8 tbsp = 1/2 cup, 12 tbsp = 3/4 cup. Memorize these three and you'll handle most cooking conversions without a calculator.
No. A US tablespoon is 14.787 mL (1/16 of a US cup), while a UK (imperial) tablespoon was historically 17.76 mL. Since 1990, the UK has officially adopted the metric tablespoon of 15 mL. Australia uses a 20 mL tablespoon. Always check which standard your recipe follows.
Dry measuring cups are designed to be filled to the brim and leveled off, while liquid measuring cups have a pour spout and extra space above the measurement line. For tablespoons, this distinction doesn't matter — one tablespoon is one tablespoon regardless of whether the ingredient is wet or dry.
A "legal US cup" (used on nutrition labels) is exactly 240 mL, slightly larger than the customary 236.588 mL cup. For practical cooking purposes, the difference (about 1.5%) is negligible. The 16-tbsp-per-cup rule applies to the customary cup.
Professional bakers strongly recommend weight (grams) over volume for precision. A cup of flour can vary by 20% depending on how it's packed. But when a recipe specifies volume, converting tablespoons to cups is still the right approach for that recipe.
