This tool helps you determine the humidity level in the air for a given temperature and dew point.
How to Use the Humidity Calculator
To use the humidity calculator, enter the temperature, dew point, and air pressure in the respective fields. Click the “Calculate” button to get the relative humidity.
How It Calculates the Results
The saturation vapor pressure is calculated using the temperature. The actual vapor pressure is calculated using the dew point. The relative humidity is derived from the ratio of the actual vapor pressure to the saturation vapor pressure.
The formula used to calculate the saturation vapor pressure (es) is:
es = 6.112 * exp((17.67 * temperature) / (temperature + 243.5))
The formula used to calculate the actual vapor pressure (e) is:
e = 6.112 * exp((17.67 * dew_point) / (dew_point + 243.5))
Finally, the relative humidity (RH) is calculated as:
RH = (e / es) * 100
Limitations
This calculator bases its calculations on the input data provided. Ensure the values are accurate and appropriate for the environmental conditions being measured. The calculator does not account for extreme conditions or any other potential atmospheric variables that may impact the actual humidity.
