METEOROLOGY – HUMIDITY & WATER VAPOUR CALCULATOR
Relative Humidity Calc
A precise tool.
What is the Relative Humidity Calc & How does it work?
Relative humidity is a measure of the amount of water vapor present in the air compared to the maximum amount that can be held at a given temperature. It is expressed as a percentage.
The formula for calculating relative humidity (RH) from dry bulb and wet bulb temperatures is given by:
The formula for calculating relative humidity (RH) from dry bulb and wet bulb temperatures is given by:
text{RH} = left(frac{e_w}{e_s}right) times 100%
e_w = water vapor pressure at wet bulb temperature
e_s = saturation vapor pressure at dry bulb temperature
e_s = saturation vapor pressure at dry bulb temperature

Frequently Asked Questions
What is relative humidity?
Relative humidity is a measure of how much water vapor is in the air compared to the maximum amount that can be held at a given temperature.
How do I calculate relative humidity?
Use the formula RH = (e_w / e_s) * 100%, where e_w is the water vapor pressure at wet bulb temperature and e_s is the saturation vapor pressure at dry bulb temperature.
What are the units for relative humidity?
Relative humidity is expressed as a percentage.
Why is relative humidity important in meteorology?
Relative humidity helps determine comfort levels, dew point, and potential for condensation or precipitation.
Can you explain the difference between dry bulb and wet bulb temperatures?
Dry bulb temperature measures air temperature without considering moisture. Wet bulb temperature is lower due to evaporation of water on a thermometer covered in a wick, indicating moisture content.
