How to Convert Teaspoons to Grams

Since teaspoons are a unit of volume and grams are a unit of mass, which are different physical quantities, we need to know one more physical quantity of the ingredient or substance to convert between them. In this case, we need to account for the density of the substance whenever we do a conversion.

Therefore, to convert between teaspoons and grams of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.

Teaspoons to Grams Formula

To convert a measurement in teaspoons to grams, multiply the volume by the density of the ingredient or material. Note that in order for this to work, the density must be in grams per teaspoon (g/tsp).

If the density is given in grams per milliliter (g/mL), then first multiply the density by 4.9289 to convert to g/tsp.

For a density given in g/mL, you can use this simple formula to convert:

grams = teaspoons × 4.9289 × density

Thus, the weight in grams is equal to the volume in teaspoons multiplied by 4.9289 times the density (in g/mL) of the ingredient, substance, or material.

For example, here's how to convert 5 teaspoons to grams for an ingredient with a density of 0.7 g/mL.
grams = 5 tsp × 4.9289 × 0.7 g/mL = 17.2512 g

When to Convert Teaspoons to Grams

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 and clumping.

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, and sugar conversion calculators.

Another useful application of weight and volume conversions is chemistry. When performing chemical reactions by combining separate chemicals to produce a new chemical, one must know the exact amount of each chemical to add in order to maximize the yield of the reaction.

It is common to mix powdered chemicals with liquid, or aqueous, chemicals, and this is where it becomes very useful to convert between weights and volumes.[2]

How Many Grams Are in a Teaspoon?

The actual weight of a teaspoon will vary depending on the density of the material. The table below shows how many grams of various wet and dry ingredients are in a teaspoon.

What Is a Teaspoon?

The teaspoon is a unit of volume equal to 1/3 of a tablespoon or 1/6 of a fluid ounce.[3] One teaspoon is equal to approximately 4.929 milliliters, but in nutrition labeling, one teaspoon is equal to exactly 5 milliliters.[4]

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.

What Is a Gram?

A gram is a unit of mass equal to 1/1,000 of a kilogram or 0.035274 ounces, and is equivalent to the mass of one cubic centimeter, or one milliliter, of water.

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

A gram is also frequently referred to as a unit of weight. While technically, a gram is a measure of mass, and weight is actually a measure of force, the two are equivalent as long as we are performing our calculations on Earth.

For example, an object with a mass of 1 gram weighs 1 gram on Earth, but only weighs one-sixth of that on the moon, yet still has the same mass.
