Conversion of kilo Newtons to kilos per square metre

Conversion of kilo Newtons to kilos per square metre   (06/28/2019, 5:26 AM)

I am laying a York stone floor o top of a DPM and am told that the dead load of weight of stone and screed will apply approx 5.2 Kn/M2 pressure on the DPM.

What is the weight of stone and screed in kilos per square meter that would apply that pressure ?

Thanks

David.
