How do I convert milliliters to tablespoons?

By Paulo de VriesLast verified 4 sources~3 min readhigh consensus

1 tablespoon (US) = 14.79 mL ≈ 15 mL. 1 mL = 0.0676 tbsp. Quick math: divide mL by 15 to get tablespoons. 30 mL = 2 tbsp; 60 mL = 4 tbsp (1/4 cup); 240 mL = 16 tbsp (1 cup).

The full answer

The conversion

1 US tablespoon = 14.7868 mL. The US tablespoon is defined as exactly 0.5 fluid ounces = 4 teaspoons. For everyday cooking, round to 15 mL per tablespoon (0.8% error).

Note: Australian + UK tablespoons differ. Australian tablespoon = 20 mL (NOT 15 mL). UK metric tablespoon = 15 mL but some older UK recipes use 17.7 mL. Always identify which standard your recipe uses.

Conversion math (mental shortcuts)

To convert mL → tbsp: divide by 15. - 45 mL ÷ 15 = 3 tbsp - 75 mL ÷ 15 = 5 tbsp - 90 mL ÷ 15 = 6 tbsp

To convert tbsp → mL: multiply by 15. - 6 tbsp × 15 = 90 mL - 12 tbsp × 15 = 180 mL

Why the precision matters

For LIQUIDS (water, oil, vinegar, milk): the 0.8% rounding error is invisible. Use 15 mL = 1 tbsp.

For BAKING with measured liquids (sourdough hydration calculations): use 14.79 mL exact. The 0.2 mL difference per tablespoon compounds across 10+ tablespoons.

For SPIRITS/COCKTAILS: use exact 14.79 mL — drink balance is sensitive to small variances.

What changes the time

  • Tablespoon standard. US: 14.79 mL. UK metric: 15 mL. Australia: 20 mL. Always check recipe origin.
  • Precision needed. Cooking: 15 mL rounding fine. Baking: use 14.79 exact. Cocktails: exact.
  • Liquid vs dry. Tablespoon is a volume measure. For dry ingredients, weighing in grams is more accurate than measuring by tablespoons.

Common questions

Is the Australian tablespoon really different from the US tablespoon?

Yes — Australian tablespoon = 20 mL; US tablespoon = 14.79 mL (about 15 mL). That is a 35% difference. If you cook from an Australian recipe in the US, "3 tbsp" of soy sauce means 60 mL, not 45 mL — that is one full extra tablespoon of saltiness. If unsure: check recipe origin and convert to milliliters.

How many milliliters in a "stick" of butter?

Butter is sold by weight, not volume — 1 US stick = 113 g = 4 oz = 8 tbsp. By VOLUME, that 8 tbsp equals 8 × 14.79 = 118 mL. But butter density (~0.91 g/mL) means 113 g of butter actually occupies about 124 mL of volume (cold solid is denser than packed measurement implies). When recipes call for mL of butter, melted, weigh 113 g and trust that = 1 stick.

My recipe says 30 mL but I only have measuring spoons — what to use?

30 mL = 2 US tablespoons. Use a 1-tablespoon measure twice, level each scoop. If you have only a 1-teaspoon measure: 30 mL = 6 teaspoons. Most measuring spoon sets include both 1-tbsp and 1-tsp; use whichever is more convenient.
