Tablespoon to Teaspoon Converter (tbsp to tsp)
1 tablespoon equals 3 teaspoons — multiply the number of tablespoons by 3 to convert to teaspoons. This clean whole-number relationship holds in the US, UK and metric spoon systems: every tablespoon is three teaspoons.
The formula
To convert tablespoons to teaspoons, multiply by the exact factor 3:
tsp = tbsp × 3
For example, 4 tbsp × 3 = 12 tsp. To reverse it, divide teaspoons by 3.
