Mixing Ratio Calculator

Enter the air temperature and dew point into the calculator to determine the 2 mixing ratios.

Mixing Ratio Formula

The following 3 formulas are used to calculate the mixing ratio of air.

MR = 6.11 X 10 ^ ( 7.5*DP/(237.7+DP))

SMR = 6.11 X 10 ^ ( 7.5*T/(237.7+T))

  • Where DP is the dew point (C)
  • T is the termpature
  • MR is the mixing ratio
  • SMR is the saturated mixing ratio

FAQ

What is a mixing ratio?

A mixing ratio is a ratio of the total mass of water vapor in air to the total mass of dry air. In other words how much water is suspended per unit of dry air.

How is mixing ratio calculated?

A mixing ratio is calculated using the temperature and dew point.
