Centigram (cg)

Mass

Exact conversion

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 Nanogram

To convert from Centigram (cg) to Nanogram (ng), multiply the value by 10,000,000.

Formula: ng = cg × 10,000,000

Reverse: cg = ng × 1.000000e-7

Step-by-Step Example

Start with your value in Centigram. For example: 5 cg
Multiply by the conversion factor: 5 x 10,000,000
The result is: 50,000,000 ng

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 Nanogram

The nanogram (ng) is a unit of mass and weight. One nanogram equals 1.000000 × 10^-12 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.
