Tablespoons to Milliliters Converter
Convert US tablespoons (tbsp) to milliliters (mL)
Tablespoon (US)
Definition: The US tablespoon (symbol: tbsp or T) is a unit of volume used primarily in cooking and baking. One US tablespoon equals exactly 14.7868 milliliters, or ½ fluid ounce. There are 3 teaspoons in 1 tablespoon, and 16 tablespoons in 1 cup.
History/origin: The tablespoon as a measurement evolved from the actual spoon used at dining tables. It was standardized in the United States as exactly ½ fluid ounce (14.7868 mL) to create consistency in recipes. The tablespoon is one of the most commonly used measurements in American cooking, sitting between the teaspoon (smaller) and the cup (larger) in the hierarchy of volume measurements.
Current use: The US tablespoon is ubiquitous in American cooking and baking recipes. It's used for measuring both liquid and dry ingredients like oil, butter, sugar, spices, and flour. The tablespoon is particularly useful for medium-sized portions that are too large for teaspoons but too small for cups. Converting tablespoons to milliliters is essential when using US recipes with metric measuring tools or adapting American recipes for international use.
Milliliter
Definition: A milliliter (symbol: mL) is a unit of volume in the metric system. One milliliter is equal to one-thousandth of a liter (0.001 L), or 1 cubic centimeter (cm³). In US measurements, one US tablespoon equals approximately 14.787 milliliters.
History/origin: The milliliter is part of the metric system, which was first introduced in France in the 1790s during the French Revolution. The metric system was designed to be universal, decimal-based, and easy to use. The prefix "milli-" means one-thousandth, making the milliliter a convenient unit for measuring small liquid volumes. The metric system, including the milliliter, was officially adopted by most countries worldwide throughout the 19th and 20th centuries.
Current use: Milliliters are the standard unit for liquid measurements in most countries worldwide. They are used extensively in cooking, baking, medicine (for dosing medications), chemistry, and everyday life. Converting tablespoons to mL is essential when using American recipes with metric measuring tools, following international cooking instructions, or understanding medication dosages that use metric measurements.

1 tbsp = 14.7868 mL (exact)
1 mL = 0.067628 tbsp
mL = tbsp × 14.7868
Quick Mental Math:
Multiply tbsp by 15 to get approximate mL
For quick estimates, you can use 1 tbsp ≈ 15 mL (within 1.5% accuracy)
Common Approximations:
1 tbsp ≈ 15 mL (very close approximation)
2 tbsp ≈ 30 mL (1 fl oz)
4 tbsp ≈ 60 mL (¼ cup)
8 tbsp ≈ 120 mL (½ cup)
Useful Relationships:
1 tablespoon = 14.7868 mL = 3 tsp = ½ fl oz
1 cup = 16 tbsp = 236.588 mL
1 teaspoon = ⅓ tbsp = 4.929 mL
¼ cup = 4 tbsp = 60 mL
