How Many Teaspoons in a Tablespoon?
There are 3 teaspoons in 1 tablespoon (US measures — 15 ml vs 5 ml). That makes half a tablespoon 1½ teaspoons, which is the practical way to halve any recipe amount given in tablespoons.

Watch for non-US spoons
A UK tablespoon is 15 ml like the US one (older UK recipes may assume 17.7 ml), but an Australian tablespoon is 20 ml — 4 teaspoons, not 3. For salt, yeast, and baking powder that 33% difference is enough to change the result, so check a recipe's origin before measuring by spoon.
Halving and doubling
½ tbsp = 1½ tsp · 1½ tbsp = 4½ tsp · 2 tbsp = 6 tsp = ⅛ cup. Going bigger, spoon math hands off to cup math at 4 tablespoons = ¼ cup — see how many tablespoons in a cup.
