Enter your weight in grams and select an ingredient — this Grams to Teaspoons Converter calculates the equivalent teaspoon volume based on each ingredient's density. Choose from common cooking staples like sugar, salt, flour, butter, and more, or enter a custom density for any other ingredient. You get the teaspoon result plus the ingredient's density used in the calculation.

It depends entirely on the ingredient. Because grams measure weight and teaspoons measure volume, you need the ingredient's density to convert between them. For example, 1 gram of water equals about 0.2 teaspoons, while 1 gram of sugar equals about 0.24 teaspoons.
10 grams of granulated sugar is approximately 2.4 US teaspoons. Granulated sugar has a density of around 0.85 g/mL, so the conversion uses the formula: teaspoons = grams ÷ (density × tsp volume in mL).
10 grams of salt is approximately 1.7 US teaspoons. Salt is denser than sugar (around 1.217 g/mL), which is why the same weight takes up less volume in teaspoons.
10 grams of baking powder equals about 2.3 US teaspoons. Baking powder has a density of roughly 0.9 g/mL, making it lighter than salt but similar to sugar in volume per gram.
Because grams are a unit of mass (weight) and teaspoons are a unit of volume. Different ingredients have different densities — a teaspoon of honey weighs much more than a teaspoon of flour because honey is far denser. Always use an ingredient-specific converter for accurate cooking measurements.
Use the standard matching your recipe's country of origin. US teaspoons hold 4.9289 mL, metric teaspoons hold exactly 5 mL, and Imperial (UK) teaspoons hold about 5.9194 mL. For most American recipes, the US teaspoon is correct. The difference is small but can matter in precise baking.
Use the formula: teaspoons = grams ÷ (density in g/mL × teaspoon volume in mL). For a US teaspoon, that's: tsp = grams ÷ (density × 4.9289). Look up your ingredient's density, or use this calculator which has densities built in for common cooking ingredients.
There are 3 teaspoons in 1 tablespoon, regardless of whether you're using US, metric, or Imperial measurements. So once you have your teaspoon value, simply divide by 3 to get tablespoons.
