What are pounds and micrograms?

Pound (lb)
Exactly 0.45359237 kilograms by international agreement, and sixteen ounces.
Microgram (mcg)
One millionth of a gram. Written mcg rather than µg on labels deliberately: the Greek letter is the character most often lost in transcription, and a factor of a thousand in a dose is not a rounding error.
