Because humidity varies with temperature and pressure...

Its a bit like saying let's call the density of a liquid 54 grams... It means nothing!!

Because the the amount of moisture the air will hold increases with an increase in temperature. Air at 100 degrees will hold more water at saturation (100% humidity) then air at 0 degrees at saturation. So humidity is relative to the temperature.
