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 Kilogram
To convert from Centigram (cg) to Kilogram (kg), multiply the value by 1.000000e-5.
Formula: kg = cg × 0.00001
Reverse: cg = kg × 100,000
Step-by-Step Example
- Start with your value in Centigram. For example: 5 cg
- Multiply by the conversion factor: 5 x 1.000000e-5
- The result is: 5.000000e-5 kg
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 Kilogram
The kilogram is the base unit of mass in the SI system. Since 2019, it is defined by the Planck constant rather than a physical artifact.
Fun Fact: Until 2019, the kilogram was defined by a platinum-iridium cylinder kept in Paris, called "Le Grand K."
Common uses: body weight, cooking, shipping.
