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.
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.
How do you convert milliliters (mL) to milligrams (mg)?
Understanding the Conversion
Converting milliliters to milligrams requires knowing the density of the substance, as mL is a unit of volume and mg is a unit of mass. The relationship between volume and mass is determined by density.
The Conversion Formula
To convert milliliters to milligrams, use the following formula:
mg = mL × density × 1000
Where density is measured in g/mL.
Step-by-Step Process
- Determine the volume in milliliters
- Find the density of your substance in g/mL
- Multiply the mL value by the density to get grams
- Multiply the result by 1000 to get mg
Examples (using water, density = 1 g/mL)
- 1 mL to mg:
1 mL × 1 × 1000 = 1000 mg - 0.5 mL to mg:
0.5 mL × 1 × 1000 = 500 mg - 0.1 mL to mg:
0.1 mL × 1 × 1000 = 100 mg - 5 mL to mg:
5 mL × 1 × 1000 = 5000 mg
Quick Reference (for water)
- 1 mL = 1000 mg
- 0.001 mL = 1 mg
- 1 L = 1,000,000 mg
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.
