Only works with Imperical Units with lbm versus lbf and 32.2ft/s^2 acceleration (on earth); same result numberically, but different units between mass and force, as you pointed out. You can convert using the famous Gc(GsubC),where…1kgm/Nm^2 = 32.2ftlbm/lbf^2 = 1ftslug/lbf*s^2 through dimensional analysis. However, there are numberial changes with SI units, 1kg = 9.81N of force which is essentially acceleration. Same cat, different way to skin it. Both systems use earth’s acceleration as the base line, but one system harmonizes with mass (Imperial) with resulting pounds-force, and the other system harmonizes with acceleration (SI) with resulting Newton.
