Default kW % conversion

We have 2 - 100kVA UPS Units. Each unit has a front display that we can go in and look at the status, utilization etc.

I can go into the Load section and it shows:

kVA 18%
kW 22%

I would like to take this information and convert it to what our monthly kWh usage is.

Here is what I have attempted:

22% * 80 kw = 17.6 * 720 (hours in month) = 12,672 kWh
Is this correct?
Thank You!!

If it runs 24/7 and the load is constant, yes.
If the load varies or is off part of the time, you have some averaging to do.

Does all your electric usage go through the UPS? If you have other power loads not on the UPS, you need to include them too.
