Formula

1 tablespoon (US) = 3 teaspoons = 14.787 mL = 0.5 fl oz 1 teaspoon (US) = 4.929 mL 1 cup = 16 tablespoons = 48 teaspoons = 236.588 mL

Example Calculation

Result: 12 tsp / 59.15 mL

4 tablespoons × 3 tsp/tbsp = 12 teaspoons. 4 tablespoons × 14.787 mL/tbsp = 59.148 mL. This also equals 1/4 cup or 2 fluid ounces.

Tips & Best Practices

Teaspoon and Tablespoon History

The teaspoon originated as the amount held by a small tea-stirring spoon in 18th century England. The tablespoon was the larger serving spoon. These were standardized in the US to exactly 1/6 and 1/2 fluid ounce respectively, creating the clean 1:3 ratio we use today.

Measurement Precision in Cooking

For salt, spices, and leavening agents (baking powder, baking soda), the difference between a teaspoon and a tablespoon is enormous — three times the amount. Accidentally using a tablespoon of salt instead of a teaspoon will make food inedible. Always double-check your spoon size.

International Spoon Sizes

The US tablespoon (14.787 mL) and the UK/metric tablespoon (15 mL) are nearly identical. The Australian tablespoon (20 mL = 4 tsp) is notably larger. When following Australian recipes (common for pavlova, lamingtons, etc.), be aware of this difference.

Frequently Asked Questions

How many teaspoons in a tablespoon?

There are exactly 3 US teaspoons in 1 US tablespoon. This is a defined relationship in the US customary system. So if a recipe calls for 1 tablespoon and you only have teaspoons, use 3 teaspoons.

How many mL is 1 tablespoon?

One US tablespoon equals 14.787 mL. This is often rounded to 15 mL for convenience. One US teaspoon equals 4.929 mL, often rounded to 5 mL.

How many tablespoons in a cup?

There are 16 US tablespoons in 1 US cup. This means 1 tablespoon = 1/16 cup. Common fractions: 4 tbsp = 1/4 cup, 8 tbsp = 1/2 cup, 12 tbsp = 3/4 cup.

Are all tablespoons the same size?

No. A US tablespoon is 14.787 mL (~15 mL). An Australian tablespoon is 20 mL. A UK tablespoon is 15 mL (same as rounded US). Always check which standard your recipe uses, especially for Australian recipes.

Should I use tablespoon abbreviation tbsp or T?

Both are used. "tbsp" or "Tbsp" means tablespoon, while "tsp" or "t" means teaspoon. Capital "T" for tablespoon and lowercase "t" for teaspoon is a common convention, but always verify. Mixing these up is a frequent cooking mistake.

Is a regular eating spoon one tablespoon?

Not reliably. Eating spoons vary widely in size. A proper measuring tablespoon holds exactly 14.787 mL. An eating tablespoon might hold anywhere from 10 to 20 mL. For accuracy, always use calibrated measuring spoons.
