A dehumidifier may or may not work for everyone. One can calculate relative humidity based on the dew point. Schiller Park, IL (60176) 37 Cloudy. Relative humidity measures the amount of water in the air in relation to the maximum amount of water vapor (moisture). The dew point will always either be the same or lower than the actual outside temperature. The more water in the vapour, the higher the humidity. Humidity refers to the air's water content, which is sometimes invisible. The time of Civil Sunset minus the time of Civil Sunrise. The actual saturation vapour pressure ratio is also known as relative humidity, where the real vapour pressure is a measurement of the amount of water vapour in a volume of air that rises with the amount of water vapour.
