Teaspoons to Tablespoons Converter (tsp to tbsp)

Scaling a recipe up turns small spoon amounts into awkward piles: tripling a dish with 1½ teaspoons of cumin gives 4½ teaspoons, which is quicker to measure as 1½ tablespoons. Three US teaspoons make exactly one US tablespoon, so dividing by 3 gives the tablespoon figure, and any remainder can stay in teaspoons.

The same arithmetic helps when reading health advice written in teaspoons. FDA describes the 2,300 mg daily sodium limit as about 1 teaspoon of table salt, and WHO describes its stricter free-sugar target as about 6 teaspoons a day, which comes to 2 tablespoons. A teaspoon here means a level measuring spoon of about 4.93 mL; household cutlery varies too much to rely on.

How to use this tool

1. Type a value in the Teaspoon box to see it in tablespoons, or type in the Tablespoon box to convert the other way.
2. Press ⇄ to swap the two units, or Load example for a typical value.
3. Check the charts below for common values; for other units, open the Cooking Measure converter.

Formula

Tablespoon (tbsp) = Teaspoon (tsp) × 0.333333333333

Teaspoon (tsp) = Tablespoon (tbsp) × 3

Both factors come from the converter's own definitions: 1 tablespoon = 3 teaspoons and 1 teaspoon = 0.333333333333 tablespoons (shown to 12 significant digits).

Example

Two conversions worked with the same factors the converter uses:

12 tsp = 4 tbsp

2.5 tbsp = 7.5 tsp

Quick mental estimate

Divide by 3 and keep the remainder as teaspoons: 10 tsp → 3 tbsp + 1 tsp, and 7 tsp → 2 tbsp + 1 tsp. Each leftover teaspoon is exactly ⅓ tablespoon, so the split is exact.

Use the converter or the charts when the exact figure matters.

The two units

Teaspoon (tsp): The US customary teaspoon is one sixth of a US fluid ounce, exactly 4.92892159375 mL, and 3 teaspoons make a tablespoon. This differs from a rounded metric measuring teaspoon of 5 mL.

Tablespoon (tbsp): The US tablespoon is half a US fluid ounce, exactly 14.78676478125 mL, and holds 3 teaspoons; 16 tablespoons make a cup. An Australian tablespoon is larger at 20 mL, so check which one a recipe uses.
