About this conversion

Teaspoons to millilitres is a small-measure cooking conversion used for spices, leavening agents, extracts, and liquid medicines. 1 US teaspoon = 4.929 ml (≈ 5 ml). Baking quantities: 1/4 tsp = 1.2 ml, 1/2 tsp = 2.5 ml, 1 tsp = 5 ml, 3 tsp = 1 tbsp = 15 ml. Liquid medicines are dosed in ml on a measuring syringe — teaspoons are imprecise and should never be used for medicine. The UK and metric teaspoon is 5 ml exactly. The US teaspoon (4.93 ml) is so close that the difference is negligible in cooking. When recipes say 'a pinch', that's typically 1/4 tsp or less.
