Baking Powder in Grams: Teaspoon & Cup Conversions
1 teaspoon of baking powder weighs 4 grams. Baking powder is almost always measured in teaspoons — most recipes call for 1–3 tsp. Always check the expiry date: old baking powder loses potency and will under-leaven your bake. The cup conversions below are included for completeness, but the teaspoon table is the most useful section on this page.
For the most accurate results, weigh your baking powder with a digital kitchen scale — the values below assume a level, unpacked cup.

Who is this useful for?
If you're an international cook following US-based recipes, you'll often encounter cup measurements for baking powder. However, many countries — including those in Europe and Asia — primarily use grams for precision. Converting baking powder to grams ensures consistent and reliable results, whether you're baking or cooking.
Why accuracy matters for baking powder
Precision is especially important when using baking powder in baking and cooking. Even small variations in weight can impact the texture, consistency, and flavour of your dish. For example, too much baking powder in a recipe can make baked goods dense, while too little may cause them to be too dry or crumbly.
Common mistakes to avoid when cooking with baking powder
- Using old baking powder that has lost its leavening power — test it by dropping a teaspoon into hot water; it should bubble vigorously.
- Confusing baking powder with baking soda — baking powder contains acid and base together, while baking soda needs an acid in the recipe to activate.
- Measuring baking powder in a damp spoon, which causes it to clump and affects accurate measurement.
