What is Relative Humidity?

The relative humidity of an air-water mixture is defined as the ratio of the partial pressure of water vapor in the mixture to the equilibrium vapor pressure of water over a flat surface of pure water[10] at a given temperature.
The relative humidity is normally expressed as a percentage; a higher percentage means that the air-water mixture is more humid. At 100% relative humidity, the air is saturated and is at its dew point.

How to Calculate Relative Humidity?

Relative Humidity calculator uses Relative Humidity = Specific Humidity*Partial Pressure/((0.622+Specific Humidity)*Vapor Pressure of Pure Component A) to calculate the Relative Humidity, Relative Humidity formula is defined as the ratio of the current amount of water vapor in the air to the maximum amount of water vapor the air can hold at a given temperature, expressed as a percentage. Relative Humidity is denoted by Φ symbol.

How to calculate Relative Humidity using this online calculator? To use this online calculator for Relative Humidity, enter Specific Humidity (ω), Partial Pressure (p_partial) & Vapor Pressure of Pure Component A (PA^o) and hit the calculate button. Here is how the Relative Humidity calculation can be explained with given input values -> 0.000319 = 0.25*3/((0.622+0.25)*2700).
