Fuel: Is it really KG?

The average fuel burn on a 737 is 2,000 - 2,500 kg per hour. Then how does this make sense:

Flight Time: 0.41

Fuel Used: 5072kg

Client:  fsacars

I believe FSAcars is exporting the fuel calculations to phpVMS as pounds, not kilograms. In fact, I am positive. Is there away to add in a conversion or change this somehow? Due to this, we are spending almost twice as much money on fuel as we should be.

Thanks!

There should be a setting in FSACARS, at least their docs show it
