Water here refers to steam. Water vapor in the air will condense into water, and water will evaporate into water vapor. There is an equilibrium (related to temperature). When the water vapor content is the maximum at a certain temperature, the relative humidity is 100%. The meaning of 60% relative humidity can be compared, which is a ratio. Under the actual general meteorological conditions, the volume fraction of water vapor is relatively small.

In addition, to correct the error of LS, absolute humidity does not refer to volume fraction, but mass-volume fraction, which is actually the density of water vapor.
