The dew point is the temperature to which air must be cooled to become saturated with water vapor.
It is a useful measurement because it correlates to the amount of water vapor in the air or in a gas.
Formula to calculate dew point.
Temperature observed should be in Celsius.
Apparently this relationship is fairly accurate for relative humidity values above 50%.
Relative humidity is a way of comparing how much humidity is present in the air compared to how much there could be.
Suppose a relative humidity of 55% was recorded in an area with a recorded temperature of 27 degrees Celsius. Calculate the area’s dew point temperature.
Therefore, your dew point temperature is 18 degrees Celsius.
