Dew Point Calculator

Dew point is the temperature at which the vapor is condensed into liquid water at a constant barometric pressure at the same rate of its evaporation. If the water is condensed in a solid surface, it is called as dew. It if it is formed on air , based on the altitude it is termed as fog or cloud. This calculator is used to find the dew point based on the temperature and relative humidity.

Additionally you can also find the environmental rating for various types of decay.

Formula:

d = ((112 + (0.9 * t))) * (RH/100)1/8 + (0.1 * t) - 112 Where, d = Dew Point t = Air Temperature RH = Relative Humidity

Example

If the temperature is 12 and relative humidity is 5 , then
d = ((112 + (0.9 * t))) * (RH/100)1/8) + (0.1 * t) - 112
d = ((112 + (0.9 * 12))) * (5/100)1/8) + (0.1 * 12) - 112
d1 =-26.3558
