Halving and Thirding a Recipe
Scaling a recipe down often leaves amounts like half a tablespoon. Converting to teaspoons makes them measurable.
| Original | Half | One third |
|---|---|---|
| 1 tbsp | 1.5 tsp | 1 tsp |
| 2 tbsp | 3 tsp | 2 tsp |
| 3 tbsp | 4.5 tsp | 3 tsp |
The Australian Exception
An Australian tablespoon is 20 ml, which is 4 teaspoons of 5 ml, not 3. Everywhere else, a tablespoon is 3 teaspoons.
