How to Convert Milligrams to Milliliters

Scales are used to measure weight

To convert a milligram measurement to a milliliter measurement, divide the weight by 1,000 times the density of the ingredient or material.

You can use this simple formula to convert:

milliliters = milligrams1,000 × ingredient density

Thus, the weight in milliliters is equal to the milligrams divided by 1,000 times the density of the ingredient or material.

For example, here's how to convert 500 milligrams to milliliters for an ingredient with a density of 0.7 g/mL.
500 mg = 5001,000 × 0.7 = 0.714285714286 ml

Milligrams and milliliters 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.

Milliliters

The milliliter is a unit of volume equal to 1 cubic centimeter, 1/1,000 of a liter, or about 0.061 cubic inches.[2]

The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for 10-3. A milliliter is sometimes also referred to as a millilitre. Milliliters can be abbreviated as ml, and are also sometimes abbreviated as mL or mℓ. For example, 1 milliliter can be written as 1 ml, 1 mL, or 1 mℓ.

Milliliters are sometimes expressed using the abbreviation cc for medical dosage, which is the abbreviation for the cubic centimeter.
