Conversion Formula

To convert teaspoons (tsp) to tablespoons (tbsp), divide the teaspoon value by 3. The formula is:

tbsp = tsp ÷ 3

This works because 1 tablespoon contains exactly 3 teaspoons. So, when you have a number of teaspoons, you split that number into groups of three to find how many tablespoons it makes. For example, converting 18 tsp:

  • Start with 18 teaspoons.
  • Divide 18 by 3 (since 3 tsp = 1 tbsp).
  • 18 ÷ 3 = 6 tablespoons.

This formula is practical in cooking or measuring liquids, where tablespoon is a larger unit than teaspoon.

Conversion Example

  • Convert 9 tsp to tbsp:
    • Take 9 teaspoons.
    • Divide by 3: 9 ÷ 3 = 3 tablespoons.
    • So, 9 tsp equals 3 tbsp.
  • Convert 15 tsp to tbsp:
    • Start with 15 teaspoons.
    • Divide 15 by 3: 15 ÷ 3 = 5 tablespoons.
    • Result: 15 tsp = 5 tbsp.
  • Convert 7.5 tsp to tbsp:
    • 7.5 teaspoons given.
    • Divide 7.5 by 3: 7.5 ÷ 3 = 2.5 tablespoons.
    • Answer: 7.5 tsp equals 2.5 tbsp.
  • Convert 24 tsp to tbsp:
    • 24 teaspoons are given.
    • Divide 24 by 3: 24 ÷ 3 = 8 tablespoons.
    • Therefore, 24 tsp = 8 tbsp.
