About Microgram (µg)
The microgram is a unit of mass equal to 10⁻⁶ grams or 10⁻⁹ kilograms — one millionth of a gram.
1 µg = 10⁻⁶ g = 10⁻⁹ kg = 0.001 mg = 1,000 ng.
To convert µg to mg: divide by 1,000. To convert µg to grams: divide by 1,000,000.
Vitamin dosages (e.g., vitamin B12: 2.4 µg/day), drug formulations, and food additive regulations.
The recommended daily intake of vitamin D is 15 µg (600 IU) — an incredibly tiny yet vital amount for bone health.
Confusing µg with mg — a 1,000× error. In medicine, this can be life-threatening. Always double-check the prefix.
In medical contexts, 'mcg' = 'µg'. If a prescription says '200 mcg', that's 0.2 mg or 0.0002 g.
