Half a Tablespoon to Teaspoons
1/2 tbsp = 1.5 tsp
= 7.4 ml | 0.25 fl oz | 0.0313 cups
Measure it: 1 tsp + 1/2 tsp
Australia: 1/2 tbsp = 2 tsp (20 ml tablespoon)
1/2 tablespoon is 1.5 teaspoons, which is 1 teaspoon plus a 1/2 teaspoon. A tablespoon holds 3 level teaspoons, so half of it is 1.5 tsp (7.4 ml, or 0.25 fl oz). No single spoon holds this amount, so measure it in two goes: one level teaspoon then one 1/2 teaspoon. Half-filling a tablespoon by eye is unreliable. If your recipe prints the decimal 0.5 tbsp, it means exactly the same quantity.
Half a tablespoon is exactly 1.5 teaspoons or 7.4 ml. This is the amount of vanilla extract in a standard single-serve mug cake recipe, the baking powder for one small batch of muffins, or the fish sauce in a small bowl of pho. The most accurate way to measure half a tablespoon is to fill a 1/2 teaspoon measure three times. In Australia, half an Australian tablespoon (10 ml) equals 2 teaspoons.
