Nanogram (ng)
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 Nanogram to Microgram
To convert from Nanogram (ng) to Microgram (µg), multiply the value by 0.001.
Formula: µg = ng × 0.001
Reverse: ng = µg × 1,000
Step-by-Step Example
- Start with your value in Nanogram. For example: 5 ng
- Multiply by the conversion factor: 5 x 0.001
- The result is: 0.005 µg
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 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
