FFS, just adopt the metric system already. And "lb" is not a force unit. Also don't capitalize unit abbreviations unless named after scientists.
It's confusing, since "pound" is used for both force and mass.
1 lbm is roughly 0.45 kg
1 lbf is the force required to accelerate a 1 slug (32.2 lbm) mass 1 ft/s^2.
Lb is force. Mass is Slug in imperial. https://en.wikipedia.org/wiki/Slug_(unit)
