One U.S. tablespoon equals three U.S. teaspoons. Multiply tablespoons by three, or divide teaspoons by three.

1. ½ tablespoon = 1½ teaspoons
2. 1½ tablespoons = 4½ teaspoons
3. 2 tablespoons = 6 teaspoons

Use marked measuring spoons. A spoon from the cutlery drawer can vary in size, and a heaped scoop can hold more than a level measure. Read tsp and tbsp carefully when scaling small amounts of seasoning or leavening. Some Australian recipes use a 20 mL tablespoon, equivalent to four 5 mL teaspoons. Check the recipe’s convention.
