About the units

Microgram (µg)

One millionth of a gram, often written “mcg” on supplement labels to avoid confusion with mg. One microgram equals 1×10⁻⁹ kilograms (kg).

Ounce (oz)

One sixteenth of a pound: exactly 28.349523125 g. Not to be confused with the fluid ounce (volume) or the troy ounce used for precious metals. One ounce equals 0.02834952313 kilograms (kg).
