How to Convert Teaspoons to Millilitres
1 teaspoon = 5 ml (technically 4.93 ml in US, rounded to 5). Multiply teaspoons by 5 to get ml. So 3 tsp = 15 ml. UK, US, Canadian and Australian teaspoons are all 5 ml standard - unlike tablespoons, the teaspoon size is consistent globally.
Most precise small-volume measurement in cooking. Used for spices, vanilla extract, baking powder, salt. Critical for baking where small differences matter (1 tsp baking soda vs 1.25 tsp can ruin a cake). Use measuring spoons, not table teaspoons - actual teaspoons vary widely in size.
