## How to Convert Milligrams to Milliliters

Since milligrams are a unit of mass and milliliters are a unit of volume, which are different physical quantities, we need to know one more physical quantity of the ingredient or substance to convert between them. In this case, we need to account for the density of the substance whenever we do a conversion.

Therefore, to convert between milligrams and milliliters of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.

### Milligrams to Milliliters Formula

To convert a measurement in milligrams to milliliters, divide the weight by the density of the ingredient or material. Note that in order for this to work, the density must be in milligrams per milliliter (mg/mL).

If the density is given in grams per milliliter (g/mL), then first multiply the density by 1,000 to convert to mg/mL.

For a density given in g/mL, you can use this simple formula to convert:

Thus, the volume in milliliters is equal to the weight in milligrams divided by 1,000 times the density (in g/mL) of the ingredient, substance, or material.

**For example,**here's how to convert 500 milligrams to milliliters for an ingredient with a density of 0.7 g/mL.

## When to Convert Milligrams to Milliliters

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 and clumping.

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.

Another useful application of weight and volume conversions is chemistry. When performing chemical reactions by combining separate chemicals to produce a new chemical, one must know the exact amount of each chemical to add in order to maximize the yield of the reaction.

It is common to mix powdered chemicals with liquid, or aqueous, chemicals, and this is where it becomes very useful to convert between weights and volumes.^{[2]}

## What is a Milligram?

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

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

A milligram is frequently referred to as a unit of weight. While technically, a milligram is a measure of mass, and weight is actually a measure of force, the two are equivalent as long as we are performing our calculations on Earth.

For example, an object with a mass of 1 milligram weighs 1 milligram on Earth, but only weighs one-sixth of that on the moon, yet still has the same mass.

## What is a Milliliter?

The milliliter is a unit of volume equal to 1 cubic centimeter, 1/1,000 of a liter, or about 0.061 cubic inches.^{[3]}

The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for thousandths, or 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.

Since one milliliter is equivalent to one cubic centimeter, milliliters are sometimes expressed using the abbreviation for a cubic centimeter (*cc*) for things such as medical dosages or engine displacements.
