25 Αυγ 2015 · 1 lbf = 32.174 lbm ft/s^2. So, the statement that people are trying to say should sound something more like “on earth, pounds-mass subject to gravity IS pounds-force!” To further illustrate this point, lets use newtons second law to calculate the force exerted by a 1 lbm object here on earth: Force=mass x acceleration
Conversion of units of measurement from physics and maths, e.g. Force - Pound inch per second squared [lb in/s²]

MKS, or SI units are based on meters (m), kilograms (kg) , and seconds (s). Pounds are used for both mass (a basic quantity, sometimes written as lbm) and force (a derived quantity, sometimes written as lbf). Under earth gravity 1 lbm weighs 1 lbf.
One pound-force (lbf) represents the force required to accelerate 1 slug of mass at 1 ft/s 2. F = slug * ft/s2 = lbf. When we apply this equation in a typical application, where the acceleration due to gravity equals approximately 32.2 ft/s 2, we find that 1 slug produces a force (sometimes referred to as “weight”) of 32.2 lbf. F = m * a.
Convert pound-force (lbf) to another unit of force such as nanonewtons, micronewtons, or millinewtons, and see the conversion formulas.
