How to Convert Centigram to Milligram
To convert cg to mg: multiply by 10. To convert cg to grams: divide by 100.
1 cg = 0.01 g = 10 mg = 10,000 µg.
For example, 1 Centigram (cg) = 10 Milligram (mg).

About Centigram (cg)
Definition
The centigram is a unit of mass equal to one hundredth of a gram (10⁻² g) or 10 milligrams.
Mathematical Relationship
1 cg = 0.01 g = 10 mg = 10,000 µg.
Conversion Formula
To convert cg to mg: multiply by 10. To convert cg to grams: divide by 100.
Practical Applications
Occasionally used in older pharmaceutical and chemical references. Most modern use has shifted to mg.
Interesting Facts
The centigram is one of the least-used metric prefixed mass units, overshadowed by the more practical milligram.
Common Mistakes
Because it's so rarely used, people may not recognize 'cg' — convert to mg for clarity in communication.
Educational Tips
Centi = hundredth: just as 1 cm = 0.01 m, 1 cg = 0.01 g. The pattern is consistent across all SI units.
About Milligram (mg)
Definition
The milligram is a unit of mass equal to one thousandth of a gram (10⁻³ g) or one millionth of a kilogram.
Mathematical Relationship
1 mg = 0.001 g = 10⁻⁶ kg = 1,000 µg. There are 1,000 mg in 1 gram.
Conversion Formula
To convert mg to grams: divide by 1,000. To convert mg to grains: multiply by 0.01543.
Practical Applications
Drug tablets (e.g., aspirin 325 mg), caffeine content (coffee ~95 mg/cup), sodium on food labels, and gemstone weights.
Interesting Facts
A single grain of sand weighs about 1 mg. The lethal dose of pure caffeine is roughly 10,000 mg (10 g) for an average adult.
Common Mistakes
Confusing mg with mL — milligrams measure mass, milliliters measure volume. They're only equal for water (density = 1 g/mL).
Educational Tips
A standard paper clip weighs about 1,000 mg (1 g). Use this to visualize what a milligram fraction looks like.
