Calculation of relative humidity Determine the saturation vapor pressure (ew), as a function of (tw) and then calculate the ratio of the vapor pressure (e) to (ew). If the vapor pressure is determined to be a minus value, consider the relative humidity to be zero. Example of calculation of relative humidity is as follows.

If I increase the relative humidity in my home in winter, can I lower the temperature and save energy? Although there is a relationship between how warm you feel and relative humidity, the human body quickly adjusts to moderate changes in humidity levels. If you feel cold at 65°F, the humidity level really won’t matter.You’ll still feel cold.
