specific humidity is defined as
specific humidity = mass of water vapor/total mass of air.
or It is the weight of water vapor (moisture) present in a unit weight of air. It is generally expressed as mg/kg.

The Absolute Humidity of a parcel of air is expressed as:
Absolute Humidity = mass of water vapor/ volume of air.
or It is the amount of water vapor present in a unit volume of air

Relative Humidity is defined as
RH = vapor pressure/saturation vapor pressure = e/es
It is the percentage ratio of the amount of moisture in a given volume or space.
