How to Convert Milligrams to Teaspoons

Scales are used to measure weight

To convert a milligram measurement to a teaspoon measurement, divide the weight by 4,928.92159 times the density of the ingredient or material.

You can use this simple formula to convert:

teaspoons = milligrams4,928.92159 × ingredient density

Thus, the weight in teaspoons is equal to the milligrams divided by 4,928.92159 times the density of the ingredient or material.

For example, here's how to convert 5,000 milligrams to teaspoons for an ingredient with a density of 0.7 g/mL.
5,000 mg = 5,0004,928.92159 × 0.7 = 1.449172 tsp

Milligrams and teaspoons 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 weight to volume conversion.

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.

Teaspoons

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.
