How to Convert Teaspoons to Kilograms

To convert a teaspoon measurement to a kilogram measurement, divide the volume multiplied by the density of the ingredient or material by 202.884136.

You can use this simple formula to convert:

kilograms = teaspoons × ingredient density / 202.884136

Thus, the volume in kilograms is equal to the teaspoons times the density of the ingredient or material divided by 202.884136.

For example, here's how to convert 500 teaspoons to kilograms for an ingredient with a density of 0.7 g/mL.
500 tsp = 500 × 0.7 / 202.884136 = 1.725123 kg

Teaspoons and kilograms 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.

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.


The definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.

The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[4] It is roughly equal to the mass of 1,000 cubic centimeters of water.

The kilogram, or kilogramme, is the SI base unit for weight and is also a multiple of the gram. In the metric system, "kilo" is the prefix for 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.
