Nanogram (ng)

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 Nanogram to Kilogram

To convert from Nanogram (ng) to Kilogram (kg), multiply the value by 1.000000e-12.

Formula: kg = ng × 1.000000e-12

Reverse: ng = kg × 1.000000e+12

Step-by-Step Example

Start with your value in Nanogram. For example: 5 ng
Multiply by the conversion factor: 5 x 1.000000e-12
The result is: 5.000000e-12 kg

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.

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.
