What are milligrams (mg)?
The milligram (mg) is a unit of mass in the metric system, equal to one-thousandth of a gram (0.001 g). It is commonly used in medicine, chemistry, and nutrition to measure small quantities of substances, such as medication doses, vitamins, or active ingredients in supplements.
The milligram is part of the International System of Units (SI) and is widely used in scientific and medical contexts around the world.
What are milliliters (mL)?
The milliliter (mL) is a unit of volume in the metric system, equal to one-thousandth of a liter (0.001 L). It is commonly used to measure liquids in cooking, medicine, chemistry, and everyday life.
One milliliter is equivalent to one cubic centimeter (1 mL = 1 cm³), making it easy to visualize and use in various applications.
How do you convert milligrams (mg) to milliliters (mL)?
Understanding the Conversion
Converting milligrams to milliliters requires knowing the density of the substance, as mg is a unit of mass and mL is a unit of volume. The relationship between mass and volume is determined by density.
The Conversion Formula
To convert milligrams to milliliters, use the following formula:
mL = mg ÷ (density × 1000)
Where density is measured in g/mL.
Simplified: mL = mg ÷ 1000 ÷ density
Step-by-Step Process
- Determine the mass in milligrams
- Find the density of your substance in g/mL
- Divide the mg value by 1000 to get grams
- Divide the result by the density to get mL
Examples (using water, density = 1 g/mL)
- 1000 mg to mL:
1000 mg ÷ 1000 ÷ 1 = 1 mL - 500 mg to mL:
500 mg ÷ 1000 ÷ 1 = 0.5 mL - 100 mg to mL:
100 mg ÷ 1000 ÷ 1 = 0.1 mL - 5000 mg to mL:
5000 mg ÷ 1000 ÷ 1 = 5 mL
Quick Reference (for water)
- 1 mg = 0.001 mL
- 1000 mg = 1 mL
- 1 g = 1 mL
Important Notes
This conversion depends entirely on the density of the substance. Water has a density of 1 g/mL, which makes the conversion simple. However, other substances have different densities:
• Olive oil: ~0.92 g/mL
• Honey: ~1.42 g/mL
• Mercury: ~13.6 g/mL
Always use the correct density for accurate conversions.
