Conversion Formula
The formula to convert teaspoons to tablespoons is straightforward: divide the teaspoon value by 3. That’s because 1 tablespoon equals 3 teaspoons, so dividing teaspoons by 3 gives the tablespoon amount.
How it works is based on volume equivalence: teaspoons and tablespoons measure volume, and since 3 teaspoons fill up 1 tablespoon, dividing allows to scale down from the smaller unit to the larger unit.
Example math:
- Given: 18 tsp
- Calculation: 18 ÷ 3 = 6 tbsp
- Result: 18 teaspoons is equal to 6 tablespoons
Conversion Example
- Convert 9 tsp to tbsp:
- Start with 9 teaspoons
- Divide by 3 (since 3 tsp = 1 tbsp)
- 9 ÷ 3 = 3 tablespoons
- Convert 12 tsp to tbsp:
- Begin with 12 teaspoons
- Divide 12 by 3
- 12 ÷ 3 = 4 tablespoons
- Convert 5 tsp to tbsp:
- Take 5 teaspoons
- Divide by 3
- 5 ÷ 3 ≈ 1.6667 tablespoons
- Convert 30 tsp to tbsp:
- 30 teaspoons
- Divide 30 by 3
- 30 ÷ 3 = 10 tablespoons
