METEOROLOGY – HUMIDITY & WATER VAPOUR CALCULATOR
Mixing Ratio
A precise tool.
What is the Mixing Ratio & How does it work?
The mixing ratio is a measure of the amount of water vapor present in air, expressed as the mass of water vapor per unit mass of dry air. It is an important parameter in meteorology and atmospheric science.
w = frac{e}{P – e}
w = mixing ratio, e = water vapor pressure, P = total air pressure
The water vapor pressure can be calculated using the dew point temperature and the saturation vapor pressure at that temperature.

Frequently Asked Questions
What is the mixing ratio in meteorology?
The mixing ratio is the mass of water vapor per unit mass of dry air, crucial for understanding atmospheric conditions.
How do I calculate water vapor pressure from dew point?
Use the formula e = 6.11 * 10^(7.5*T_d / (T_d + 237.3)), where T_d is the dew point temperature in Celsius.
Can you explain how to use this mixing ratio calculator?
Input the dew point temperature and total air pressure to get the mixing ratio of water vapor in the air.
What units should I use for the inputs?
Use Celsius for dew point temperature and millibars or atmospheres for total air pressure.
Why is the mixing ratio important in atmospheric science?
It helps in predicting weather conditions, understanding humidity levels, and studying cloud formation.
How does the mixing ratio change with temperature?
As temperature increases, the saturation vapor pressure increases, potentially raising the mixing ratio if air is saturated.
Can this calculator be used for any gas besides water vapor?
This specific calculator is designed for water vapor in air. For other gases, a different formula would be required.
