About this teaspoons to ml tool
The teaspoon is one of the most consistent small measurements in cooking. Unlike tablespoons, which vary between countries, a teaspoon is universally 5ml in UK, US, Australian and metric cooking. This makes teaspoon-to-ml conversion straightforward: simply multiply the number of teaspoons by 5.
Teaspoons commonly appear in recipes for vanilla extract, baking powder, bicarbonate of soda, dried spices, and salt. These small quantities are important to get right, especially in baking where leavening agents like baking powder have a precise effect on the recipe's outcome.
The relationship between teaspoons and tablespoons is simple: 3 teaspoons = 1 tablespoon = 15ml. And 48 teaspoons = 1 US cup (240ml). These conversions are worth memorising for quick kitchen maths without a calculator.
For very small quantities like ¼ teaspoon (1.25ml) or ⅛ teaspoon (0.625ml), kitchen measuring spoons are the most accurate tool. Digital scales that read to 0.1g are even more precise for critical baking ingredients like baking soda.
