How to output humidity ratio of zone in EnergyPlus?

Is there an option to output humidity ratio (g/kg or absolute humidity g/m3) of Zone from EnergyPlus simulation as output variable? Does anyone have experience with that? Or do I have to calculate those values from relative humidity?

There is an output Zone Mean Air Humidity Ratio. You can add it to the Output:Variable of your model.

The unit is kgWater/kgDryAir.

Great, thank you! Now I know it is there, I found it in the documentation. But I think it should be Zone Air Humidity Ratio (without the Mean) ... at least according to the Input Output Reference ? documentation

In the .rdd I have both. It's the same for Zone Air Temperature and Zone Mean Air Temperature which give the same results. It may show some differences with specific timesteps.
