Convert Liters to Milligrams: The Comprehensive Guide

Understanding the Units

The liter (L) is a metric unit of volume, while the milligram (mg) is a metric unit of mass. One liter is equivalent to 1,000 cubic centimeters (cm³) or 1,000 milliliters (mL). One milligram is equal to one-thousandth of a gram (g), or 0.001 g.

Conversion Formula

To convert liters to milligrams, you can use the following formula:

Milligrams = Liters × Density

where density is the mass of a substance per unit volume.

Density Values

The density of a substance varies depending on its composition and temperature. Here are some common densities at room temperature:

Converting for Common Substances

Water

To convert liters of water to milligrams, multiply the number of liters by 1,000 (the density of water in g/mL):

Milligrams of Water = Liters of Water × 1,000 g/mL

For example, 2 liters of water is equivalent to 2,000,000 mg.

Milk

To convert liters of milk to milligrams, multiply the number of liters by 1,030 (the density of milk in g/mL):

Milligrams of Milk = Liters of Milk × 1,030 g/mL

For example, 1 liter of milk is equivalent to 1,030,000 mg.

Gasoline

To convert liters of gasoline to milligrams, multiply the number of liters by 740 (the density of gasoline in g/mL):

Milligrams of Gasoline = Liters of Gasoline × 740 g/mL

For example, 5 liters of gasoline is equivalent to 3,700,000 mg.
