Milligram (mg)
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 Milligram to Nanogram
To convert from Milligram (mg) to Nanogram (ng), multiply the value by 1,000,000.
Formula: ng = mg × 1,000,000
Reverse: mg = ng × 0.000001
Step-by-Step Example
- Start with your value in Milligram. For example: 5 mg
- Multiply by the conversion factor: 5 x 1,000,000
- The result is: 5,000,000 ng
About Milligram
The milligram equals one thousandth of a gram and is the standard unit for drug dosage and nutrient quantities.
Common uses: medication dosage, nutrition labels, laboratory work.
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.
