The amount of water vapour present in the air expressed as a percentage of the amount needed for saturation at the same temperature/ Is the ratio of the actual partial vapour pressure of water to the saturation vapour pressure at that temperature or in very simplified terms the ratio of water in the specific atmosphere. Conservators control RH when trying to reach the optimum environmental conditions for materials.
