===Meaning===
A [[microgram]] (µg) is a [[unit]] of [[mass]] which is 1000,000,000 times smaller than the [[SI Unit]] for [[mass]], the [[kilogram]].
===About Microgram===
: A [[microgram]] is shortened to the Greek letter µ with a lower case g '''µg'''.
: [[Micro]] refers to one millionth as there are one million [[microgram]]s in a [[gram]].
