probably b\c they are two different units of measurment. A CC is a unit of Volume. a microgram is a unit of mass.
so 1 CC of water weighs something different from 1 CC of another liquid because liquids have different weights. a box full of feathers would weigh something different than that same sized box full of bricks, wouldnt it?
Just for the sake of conversation though, 1CC of water happens to weigh 1 gram. so in this case there would be 1.0 x10^6 (1 million) micrograms in 1CC of water.
