25 sie 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

What is the weight, in lbf of a circular PMMA (plexiglass) cylinder, 15 mm diameter and 130 mm long? You need to know the density of PMMA. It is approximately 1.2 g/cm3. Weight in US units equals the mass in US units, so the weight is 0.068 lbf. You can approximate most unit conversions in your head if you can recall a few basic results.
