Dew Point: The dew point is the temperature at which condensation starts to form; technically speaking it is temperature to which the air would have to cool (at constant pressure and constant water vapour content) in order to reach saturation.
Relative Humidity: The relative humidity is a measure of how mush moisture is in the air; technically speaking it is the ratio of the water vapour density (mass per unit volume) to the saturation water vapour density.
possible uses of these calculators:
Determining the minimum surface temperature required to prevent condensation forming.
To determine the maximum humidity before condensation will start to form at a given a surface temperature.
