Full Answer >To convert kN/m2 to kg/m2, multiply by approximately 102 seconds squared per meter, which is 1000/9.8 seconds squared per meter. The conversion of units of force, such as kilonewtons, to units of mass, such as kilograms, assumes that the mass is subject to an acceleration, most often the acceleration of gravity, which is typically around 9.8 meters per second near the earth's surface. However, the precise figure can vary slightly with location.
