To convert teaspoons to tablespoons, divide by 3. 3 tsp is 1 tbsp, 6 tsp is 2 tbsp, and 4 tsp is 1⅓ tbsp (1 tbsp plus 1 tsp).
When you double or triple a recipe, spoonfuls of spices and leaveners add up fast. Switching to tablespoons means fewer scoops and fewer counting mistakes.
How to use the teaspoons to tablespoons converter
- Type the value in teaspoons into the box. Decimals are fine.
- The result in tablespoons updates as you type, along with the working.
- Need the other way? Switch the direction menu, or open the tablespoons to teaspoons converter.
Formula
In US customary measure, 1 tablespoon is exactly 3 teaspoons (½ fl oz, about 14.79 mL). Metric spoons keep the same ratio: 15 mL and 5 mL. The exception is Australia, where the standard tablespoon is 20 mL, or 4 teaspoons.
Worked example
You're tripling a recipe that needs 2 teaspoons of baking powder.
- 2 tsp × 3 = 6 tsp.
- 6 ÷ 3 = 2.
- Result: 2 tablespoons.

Leftovers that don't divide evenly
When the teaspoons aren't a multiple of 3, measure whole tablespoons plus the remainder in teaspoons: 5 tsp = 1 tbsp + 2 tsp, 7 tsp = 2 tbsp + 1 tsp. 48 teaspoons make a full cup.
For medicine, use the dosing syringe or cup that comes with it. A medical teaspoon is defined as 5 mL, and kitchen spoons aren't accurate enough for dosing.
Quick mental math
Group in threes. 10 tsp: three groups of 3 is 3 tbsp, with 1 tsp left over.
