To convert a tablespoon measurement to a milligram measurement, multiply the volume by 14,786.76478 times the density of the ingredient or material.

You can use this simple formula to convert:

milligrams = tablespoons × 14,786.76478 × ingredient density

Thus, the volume in milligrams is equal to the tablespoons multiplied by 14,786.76478 times the density of the ingredient or material.

For example, here's how to convert 5 tablespoons to milligrams for an ingredient with a density of 0.7 g/mL.
5 tbsp = 5 × 14,786.76478 × 0.7 = 51,753.67674 mg

Tablespoons and milligrams 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.

Tablespoons

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.

Milligrams

The milligram is the mass equal to 1/1,000 of a gram, or 0.0154 grains.

The milligram, or milligramme, is an SI unit of weight in the metric system. In the metric system, "milli" is the prefix for 10-3. Milligrams can be abbreviated as mg; for example, 1 milligram can be written as 1 mg.
