Tablespoon (US) to Teaspoon (US) (Tablespoon (US) to Teaspoon (US))
Result
3 Teaspoon (US)
Formula
Teaspoon (US) = Tablespoon (US) × 3
1 Tablespoon (US) = 3 Teaspoon (US), and 1 Teaspoon (US) = 0.3333333333 Tablespoon (US).
Kitchen volumes here are US customary measures: 1 cup = 236.588 mL, 1 tablespoon = 14.787 mL, 1 teaspoon = 4.929 mL, 1 fluid ounce = 29.574 mL. Weights use the avoirdupois ounce and pound.
Worked examples
- 1 Tablespoon (US) × 3 = 3 Teaspoon (US)
- 10 Tablespoon (US) × 3 = 30 Teaspoon (US)
- 100 Tablespoon (US) × 3 = 300 Teaspoon (US)
Common mistakes
- Cups measure volume and grams measure weight. Converting between them depends on the ingredient: a cup of flour weighs roughly 120–130 g, a cup of sugar about 200 g.
- Cup sizes vary: US customary 236.6 mL, US nutrition label 240 mL, metric (Australia, Canada, UK recipes) 250 mL.
- An Australian tablespoon is 20 mL (four teaspoons), not 15 mL.
