Relative Humidity Calculation:
Where \( e \) is the actual vapor pressure and \( e_s \) is the saturation vapor pressure.

Relative humidity (RH) is the ratio of the current amount of water vapor in the air to the maximum amount that could be present at that temperature. It is expressed as a percentage and is calculated using temperature and dew point measurements.
The calculator uses the standard relative humidity formula:
Where:
Explanation: The formula compares the amount of moisture currently in the air with the maximum moisture the air could hold at the given temperature.
Details: Accurate humidity calculation is essential for weather forecasting, climate studies, agricultural planning, industrial processes, and maintaining comfortable indoor environments.
Tips: Enter temperature and dew point in degrees Celsius. Both values are required for accurate humidity calculation. Ensure measurements are taken from reliable instruments.
Q1: What is the relationship between temperature and humidity?
A: Warmer air can hold more moisture than cooler air. As temperature increases, relative humidity decreases if the moisture content remains constant.
Q2: What are typical relative humidity ranges?
A: Comfortable indoor humidity ranges from 30% to 50%. Below 30% may feel dry, while above 60% can feel muggy and promote mold growth.
Q3: How does dew point relate to humidity?
A: Dew point is the temperature at which air becomes saturated and condensation begins. Higher dew points indicate more moisture in the air.
Q4: Why is humidity important for health?
A: Proper humidity levels help maintain respiratory health, prevent dry skin, and reduce the spread of airborne viruses.
Q5: How accurate is this calculation method?
A: This method provides good estimates for most practical applications, though specialized instruments may be needed for highly precise measurements.
