Dew Point Calculator

The dew point is the temperature to which the air must be cooled in order for the water vapor contained in it to reach the saturation limit. In other words, so that the relative humidity of the gas is 100%. Further inflow of water vapor or cooling of the air causes condensation to form. At positive temperatures - dew, at negative temperatures - frost, ice or sleepга.
