How to Convert Tablespoons to Kilograms

Scales are used to measure weight

To convert a tablespoon measurement to a kilogram measurement, divide the volume multiplied by the density of the ingredient or material by 67.628045.

You can use this simple formula to convert:

kilograms = tablespoons × ingredient density67.628045

Thus, the volume in kilograms is equal to the tablespoons times the density of the ingredient or material divided by 67.628045.

For example, here's how to convert 5 tablespoons to kilograms for an ingredient with a density of 0.7 g/mL.
5 tbsp = 5 × 0.767.628045 = 0.051753676737 kg

Tablespoons 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 tablespoon is a unit of volume equal to three teaspoons or ½ fluid ounce.[2] One tablespoon is equal to just under 14.8 milliliters, but in nutrition labeling, one tablespoon is equal to 15 milliliters.[3]

The tablespoon is a US customary unit of volume. Tablespoons can be abbreviated as tbsp, and are also sometimes abbreviated as T, Tbls, or Tb. For example, 1 tablespoon can be written as 1 tbsp, 1 T, 1 Tbls, or 1 Tb.


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.
