THE HUMIDITY/MOISTURE HANDBOOK - MAC Instruments
Since air is seldom totally without water vapor, the above percentages change depending on the amount of water vapor that is mixed with other gases. As we have already stated, 50% RH @ 60°F corresponds to .87% water vapor. 50% RH @ 95°F corresponds to 2.8% moisture by volume, and 100% RH @ 95°F is a moisture level of 5.6% by volume.
