Which physical quantity uses kN/m2 as a unit of measurement ?

Question

Not sure what its asking for...

Answer 1

Pressure = Force / area

Force = Newtons (N)

Area = m2              

Answer 2

Assuming that you mean kN/m^2, it could be either pressure or stress.

Answer 3

It means  kilonewton per square meter

It is the unit to measure pressure

P (pressure) = F(force)\A(area)

where F is measured in kn it means 1000 newton

and area is measured in meter squared

so

P is measured in kn\m²
