Unit of measure KGF

I need to create an MIC with UoM KGF. When I look in the list of available UoMs in transaction QS21, I cannot see it.

But if I check table T006, it is there but with technical name of KG/M2

I can't see anything for this UoM in change logs, so is it standard config?

I don't believe KGF is the same as KG/M2?
