Baking Conversion Calculator
Convert cups, tablespoons and teaspoons to grams for common baking ingredients — useful for precise, repeatable baking.
How to use the baking conversion calculator
- Enter the amount from the recipe.
- Choose the unit of measure — cup, tablespoon (tbsp) or teaspoon (tsp). 1 cup = 16 tbsp = 48 tsp.
- Choose which ingredient it is — grams per cup varies a lot depending on the ingredient's density.
Why does grams per cup vary so much?
A "cup" is a volume measure, not a weight measure — so how many grams a cup equals depends entirely on how densely the ingredient is packed. One cup of butter weighs more than double one cup of flour, since butter is far denser:
This is why there's no single universal "cup to grams" conversion — the correct figure always depends on which ingredient is involved.
Frequently asked questions
Why isn't 1 cup of flour the same as 1 cup of sugar in grams?
Because a cup measures volume, not weight. Flour is lighter and less densely packed than sugar, so a given volume of flour weighs less than the same volume of sugar.
Why should I weigh instead of measuring in cups when possible?
Because how flour is packed into a measuring cup (packed down versus loosely spooned) can cause up to a 20–25% variation in actual weight. A kitchen scale gives a far more consistent and accurate result, especially important in baking where ratios between ingredients matter a lot.
What's the difference between tbsp and tsp?
A tablespoon (tbsp) is 3 times the size of a teaspoon (tsp) in the US measuring system — 1 tbsp = 3 tsp = 1/16 cup, while 1 tsp = 1/48 cup.
