Formula
RH = 100 {e^[17.625 x T(d)/243.04+T(d)]/ e^[17.625 x T(a)/243.04+T(a)]}
Where RH is relative humidity
e = exponential value = 2.7182818284590452353602874713527
T(d) = dew temperature
T(a) = air temperature
What is Relative Humidity?
Relative humidity is the proportion of the partial pressure of water vapor in the air to the maximum potential water vapor pressure at a specific temperature. Represented as a percentage, it serves as an indicator of how near the air is to reaching saturation with moisture.

FAQs
What is Dew Temperature (T(d))?
Dew temperature occurs as the air becomes saturated with moisture, causing water vapor to condense into dew. As the air cools, it reaches a critical point where its capacity to retain moisture diminishes, leading to the formation of dew on various surfaces such as grass or car windows.
The dew temperature is a crucial factor in meteorology, agriculture, and environmental science, as it indicates the point at which dew or frost may form.
What is air temperature (T(a))?
Air temperature is the measure of the warmth or coldness of the air in a specific location at a given moment. It is a key parameter in weather forecasting, climate studies, and various industries. Air temperature influences weather patterns, the behavior of gases in the atmosphere, and the comfort levels of living organisms.
How does relative humidity affect weather conditions?
Relative humidity influences cloud formation, precipitation, and overall atmospheric stability. High humidity can lead to the formation of clouds and potentially precipitation.
Can this calculator be used for indoor environments?
Yes, HVAC professionals can use this calculator to assess and control indoor humidity levels for optimal comfort and energy efficiency.
Is there a maximum limit to relative humidity?
Yes, Relative humidity is capped at 100%, representing fully saturated air.
Conclusion
The Relative Humidity Calculator is a valuable tool for various professionals and enthusiasts, providing quick and precise calculations for understanding humidity levels. Whether for weather forecasting, agricultural planning, HVAC optimization, or educational purposes, this calculator enhances decision-making and insights into environmental conditions.
