Centigram (cg)
Mass
Traceable to the kilogram, defined by fixing the Planck constant at 6.626 070 15 × 10⁻³⁴ J·s. Avoirdupois masses derive from the 1959 international pound (0.453 592 37 kg exactly).

How to Convert Centigram to Microgram
To convert from Centigram (cg) to Microgram (µg), multiply the value by 10,000.
Formula: µg = cg × 10,000
Reverse: cg = µg × 0.0001
Step-by-Step Example
- Start with your value in Centigram. For example: 5 cg
- Multiply by the conversion factor: 5 x 10,000
- The result is: 50,000 µg
About Centigram
The centigram (cg) is a unit of mass and weight. One centigram equals 1.000000 × 10^-5 kilograms. UnitConvertLab converts it against every other mass unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: mass calculations, engineering and science, education.
About Microgram
The microgram (µg) equals one millionth of a gram. Vitamins, hormones and trace contaminants are dosed at this scale.
Fun Fact: Clinical writing spells out "microgram" rather than using µg to avoid dosing errors.
Common uses: pharmacology, vitamin dosing, toxicology.
Frequently Asked Questions
