- Question
- How do I convert milliliters to tablespoons?
- Answer
- 1 US tablespoon = 14.787 mL; 1 metric tablespoon = 15 mL (the difference is negligible in cooking). So tbsp = mL / 14.787 for US, or mL / 15 for metric. 30 mL ≈ 2 tbsp, 45 mL ≈ 3 tbsp, 60 mL = 4 tbsp = ¼ cup. Going the other way, mL = tbsp × 14.787.

- Formula
tbsp = mL / 14.787 (US) or mL / 15 (metric)- Caveats
- Australian tablespoon = 20 mL. Use that factor for Australian recipes.
- UK recipes traditionally use 17.76 mL tablespoon, though most modern recipes use 15 mL.
- Measuring-spoon accuracy is ±5%; scales beat spoons for amounts over a few tablespoons.
Milliliters to Tablespoons Conversion Table
Using the US tablespoon (14.787 mL) and the Australian tablespoon (20 mL) for comparison.
| Milliliters | US Tbsp | Metric Tbsp (15 mL) | AU Tbsp (20 mL) | Teaspoons |
|---|---|---|---|---|
| 5 mL | ⅓ tbsp | ⅓ tbsp | ¼ tbsp | 1 tsp |
| 10 mL | ⅔ tbsp | ⅔ tbsp | ½ tbsp | 2 tsp |
| 15 mL | 1 tbsp | 1 tbsp | ¾ tbsp | 3 tsp |
| 20 mL | 1⅓ tbsp | 1⅓ tbsp | 1 tbsp | 4 tsp |
| 30 mL | 2 tbsp | 2 tbsp | 1½ tbsp | 6 tsp |
| 45 mL | 3 tbsp | 3 tbsp | 2¼ tbsp | 9 tsp |
| 60 mL | 4 tbsp | 4 tbsp | 3 tbsp | 12 tsp |
| 75 mL | 5 tbsp | 5 tbsp | 3¾ tbsp | 15 tsp |
| 100 mL | 6¾ tbsp | 6⅔ tbsp | 5 tbsp | 20 tsp |
| 125 mL | 8½ tbsp | 8⅓ tbsp | 6¼ tbsp | 25 tsp |
| 150 mL | 10 tbsp | 10 tbsp | 7½ tbsp | 30 tsp |
| 250 mL | 17 tbsp | 16⅔ tbsp | 12½ tbsp | 50 tsp |
What This Calculator Does
Converts between milliliters and tablespoons using the US/metric convention of 15 mL = 1 tbsp. Converts in both directions — type a mL figure to get tablespoons, or type tablespoons to get mL. Recipes from the EU, US, and Canada all share this 15 mL tablespoon; UK and Australia use a 20 mL tablespoon that needs a different factor.
When To Use This Calculator
Converting a mL-based vinaigrette to US tablespoons
Recipe calls for 45 mL olive oil — the converter returns 3 tbsp.
Measuring a small quantity of a liquid medication or extract
A recipe needs 1 tsp (5 mL) vanilla but you only have a mL dropper — 5 mL = ⅓ tbsp.
Scaling up a recipe given in tablespoons for a graduated jug
Doubling a 4 tbsp dressing: 4 tbsp × 2 × 15 = 120 mL — easier to pour into a jug.
Cross-checking a recipe from an unknown region
Recipe says '1 tbsp' but lists 20 mL in the same line — that's the UK/AU 20 mL convention, not US.
How It Works
The US tablespoon is defined as exactly 14.787 mL (½ US fluid ounce, 29.574 mL ÷ 2). Nutrition labeling and metric culinary usage round to 15 mL, which is the figure used here and by Codex Alimentarius and EU cookbooks. The UK imperial tablespoon is 17.758 mL, but most modern UK/AU cookbooks use a deliberately rounded 20 mL metric tablespoon. Converting in either direction is a single multiplication or division by 15.
Formula
mL = tbsp × 15 | tbsp = mL ÷ 15 (US/metric cooking convention)Real-World Example
Scenario
You are making an Italian pesto that calls for 60 mL olive oil, 15 mL lemon juice, and 30 mL grated parmesan. You only have US measuring spoons.
Calculation
Olive oil: 60 ÷ 15 = 4 tbsp. Lemon juice: 15 ÷ 15 = 1 tbsp. Parmesan: 30 ÷ 15 = 2 tbsp. Total 7 tbsp (≈ ⅜ cup).
Result
4 tbsp olive oil, 1 tbsp lemon juice, 2 tbsp parmesan — identical to the mL recipe, measured with US spoons.
Common Mistakes to Avoid
Mistake: Using a UK or Australian tablespoon with a US recipe
Solution: The UK/AU metric tablespoon is 20 mL. Using it for a 15 mL US recipe overshoots by 33% per tablespoon — significant in bold flavors like vanilla, soy, or chili paste.
Mistake: Confusing fluid ounces with weight
Solution: 1 US fl oz is 29.574 mL (≈ 30 mL) of volume, not 28.35 g of weight. For water they nearly coincide; for oil or honey they do not.
Mistake: Assuming all 'teaspoon = 5 mL' references match your spoon
Solution: Cheap flatware teaspoons vary from 2.5 to 7 mL. Use a proper nested measuring-spoon set or a scale.
Mistake: Measuring viscous liquids by tablespoon and expecting precision
Solution: Honey, molasses, and nut butters cling to the spoon. For ±5% precision use a scale; or lightly oil the spoon first to release the pour.

When This Isn't the Right Tool
UK imperial or Australian metric tablespoons
Use instead: Those are 17.758 mL and 20 mL respectively. For AU, multiply tablespoons by 20; for UK imperial, by 17.758.
Medical dosing
Use instead: Use a calibrated oral syringe graduated in mL. A kitchen tablespoon is not accurate enough and varies by spoon design.
Converting weight to volume
Use instead: Use a density-aware tool (ml-to-grams or ingredient-density) because 15 mL of honey weighs ~21 g while 15 mL of oil weighs ~14 g.
How to Verify This Calculation
Check that 30 mL = 2 tbsp and 240 mL = 16 tbsp (1 US cup). If the result is off by exactly 4/3 ≈ 1.33, the recipe is probably using a 20 mL UK/AU tablespoon instead.
