Kilonewton/Square Meter : The kilonewton per square meter (kN/m2) is a non-SI unit for pressure. 1 kN/m2 equals 1,000 N/m2. Pressure is defined as force per area and the SI unit for force is Newtons(N) and the SI unit for area is square meters(m2). 1 Newton per square meter equals 1 Pascal, therefore, 1 kN/m2 =1000 Pa.
