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