How to Convert Liters to Milligrams

Scales are used to measure weight

To convert a liter measurement to a milligram measurement, multiply the volume by 1,000,000 times the density of the ingredient or material.

You can use this simple formula to convert:

milligrams = liters × 1,000,000 × ingredient density

Thus, the volume in milligrams is equal to the liters multiplied by 1,000,000 times the density of the ingredient or material.

For example, here's how to convert 5 liters to milligrams for an ingredient with a density of 0.7 g/mL.
5 l = 5 × 1,000,000 × 0.7 = 3,500,000 mg

Liters 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.

How Many Milligrams are in a Liter?

The actual weight of a liter will vary depending on the density of the material. The table below shows how many milligrams of various wet and dry ingredients are in a liter.

Liters

A liter is a unit of volume equal to 1,000 cubic centimeters.[2] The liter is a special name defined for the cubic decimeter and is exactly equal to the volume of one cubic decimeter.

The liter is an SI accepted unit for volume for use with the metric system. A liter is sometimes also referred to as a litre. Liters can be abbreviated as l, and are also sometimes abbreviated as L or . For example, 1 liter can be written as 1 l, 1 L, or 1 ℓ.

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.
