How to Convert Teaspoons to Grams

To convert a teaspoon measurement to a gram measurement, multiply the volume by 4.928922 times the density of the ingredient or material.

You can use this simple formula to convert:

grams = teaspoons × 4.928922 × ingredient density

Thus, the volume in grams is equal to the teaspoons multiplied by 4.928922 times the density of the ingredient or material.

For example, here's how to convert 5 teaspoons to grams for an ingredient with a density of 0.7 g/mL.
5 tsp = 5 × 4.928922 × 0.7 = 17.251226 g

Teaspoons and grams are both commonly used to measure cooking ingredients.

For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.

The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the volume to weight conversion.

For cooking and baking ingredients, you can get more specific results using our butter, flour, sugar conversion calculators.

The teaspoon is a unit of volume equal to one-third of a tablespoon.[2] One teaspoon is equal to around 4.9 milliliters, but in nutrition labeling, one teaspoon is equal to exactly 5 milliliters.[3]

The teaspoon is a US customary unit of volume. Teaspoons can be abbreviated as tsp, and are also sometimes abbreviated as t, ts, or tspn. For example, 1 teaspoon can be written as 1 tsp, 1 t, 1 ts, or 1 tspn.


A gram is the mass/weight equal to 1/1,000 of a kilogram and is roughly equivalent to the mass of one cubic centimeter of water.

The gram, or gramme, is an SI unit of weight in the metric system. Grams can be abbreviated as g; for example, 1 gram can be written as 1 g.
