Microgram (µg)

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).

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 Scruple

The scruple (scr) is a unit of mass and weight. One scruple equals 0.0012959782 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.
