Formula

Multiply the value in tablespoons by 14.8. For the reverse direction, multiply by 0.067568.

Forwardml = tbsp × 14.8
Reversetbsp = ml × 0.067568
Example: 10 tbsp × 14.8 = 148 ml

Tips

Use these in everyday conversions
  • US tbsp = 15 ml (practical); 14.787 ml (legal); 3 teaspoons in any system.
  • Australian tablespoon = 20 ml — 33% larger. Adjust when using Australian recipes.
  • For accurate cooking, weigh dry ingredients rather than measuring by tablespoon.

Common Mistakes

Avoid these
  • Using an Australian tablespoon (20 ml) for a US recipe (15 ml) — 33% overshoot.
  • Treating teaspoon and tablespoon as interchangeable — tablespoon is 3× larger.
  • Using a dinner spoon from the cutlery drawer as a tablespoon — they vary widely.

About Tablespoon and Milliliter

What is the Tablespoon?

The tablespoon equals exactly 15 milliliters (international culinary standard) or about 14.787 mL (US strict definition based on ½ fluid ounce). The tablespoon is a near-universal cooking measure for ingredients larger than a teaspoon but smaller than a cup — typical uses include oils, sauces, and condiments. The Australian tablespoon is uniquely 20 mL (4 teaspoons rather than 3), an oddity in international recipe interpretation. Standard recipes assume 1 tbsp = 15 mL globally except in Australia and the United States (where it is sometimes 14.787 mL but commonly rounded to 15 mL). The tablespoon relates to the teaspoon (3 tsp = 1 tbsp), the cup (16 tbsp = 1 cup), the fluid ounce (2 tbsp = 1 US fl oz), and the milliliter (1 tbsp = 15 mL conventional). Measuring spoons are calibrated to the local convention.

  • Cooking recipes worldwide (dominantly US 15 ml)
  • Nutrition-label serving sizes
  • Over-the-counter liquid-medication doses
Real-world examples

Olive-oil recipes call for tablespoons of oil. Cough syrups often recommend 1 tbsp = 15 ml per dose.

What is the Milliliter?

The milliliter equals one thousandth of a liter (0.001 L) and is the standard small-volume unit for cooking, pharmaceuticals, cosmetics, and laboratory work. One milliliter is exactly 1 cubic centimeter (1 cm³), a convenient relationship: 1 mL of pure water weighs 1 gram. The milliliter is the universal unit on medicine bottles (a typical cough syrup dose is 5 mL), cosmetics (a perfume bottle is 50–100 mL), and recipe measurements outside North America (a tablespoon is 15 mL, a teaspoon is 5 mL). Medical syringes are calibrated in mL, and IV drip rates are computed in mL per hour. The milliliter relates to the liter (1,000 mL = 1 L), the cubic centimeter (1 mL = 1 cm³ = 1 cc), the teaspoon (1 tsp = 5 mL), and the US fluid ounce (1 fl oz ≈ 29.57 mL).

  • Liquid medication dosing in syringes
  • Precise cooking and baking measurements
  • Laboratory reagent measurement
Real-world examples

A teaspoon holds about 5 ml. An espresso shot is 25–30 ml. An insulin pen delivers 0.1 ml increments.
