Formula: 1 tbsp × 3 = 3 tsp

How the tablespoons to teaspoons conversion works

A US tablespoon is defined as exactly 3 US teaspoons, so the conversion is a single multiplication: tsp = tbsp × 3. Going the other way, tbsp = tsp ÷ 3.

Worked example: a recipe calling for 4 tbsp of lemon juice needs 4 × 3 = 12 tsp. Half a teaspoon is 0.5 ÷ 3 ≈ 0.167 tbsp.

Like cups to tablespoons, this ratio is exact — no rounding and no density involved. It completes the spoons triangle with our tablespoons to ml and teaspoons to ml converters.
