How many teaspoons are in one tablespoon?

Exactly 3 teaspoons equal 1 tablespoon in the US customary system. The same 3:1 ratio applies in the imperial system, and metric tablespoons (15 mL) also equal 3 metric teaspoons (5 mL each) (note that Australian tablespoons uniquely equal 4 teaspoons, or 20 mL).

How do I convert teaspoons to tablespoons?

Divide the number of teaspoons by 3. For example, 6 teaspoons ÷ 3 = 2 tablespoons. You can also type directly in the teaspoons field above and the tablespoon result appears instantly.

How many tablespoons is half a teaspoon?

Half a teaspoon equals approximately 0.1667 tablespoons (1/6 of a tablespoon). In practice, this is usually left as ½ tsp in recipes since tablespoon measures do not subdivide that finely.

How many teaspoons make a quarter tablespoon?

A quarter tablespoon (¼ tbsp) equals 0.75 teaspoons, which is ¾ tsp. This is a common measurement for small amounts of salt, baking powder, or vanilla.

Does this work for both US and metric measurements?

Yes — the 3:1 ratio holds for both US customary (1 tbsp = ~14.8 mL, 1 tsp = ~4.9 mL) and metric (1 tbsp = 15 mL, 1 tsp = 5 mL). The converter uses the ratio directly, so it is accurate for everyday cooking in any system.
