    But weight is gravitational force not mass. These are deeply related but not the same because us customary is based on pre Newtonian measurement systems

      If you say that something “weighs” something, that’s a description of mass, not weight, because the wording is from before a time when it was understood that mass and weight are different things.

      All has been said that needs to be said, bloody pedant.

        I was mostly just joking. Of course we use lbs as pseudomass. Fuck, we’ve moved to lbm vs lbf in America because mechanical engineers must be stopped and metricated by force if necessary. We’re a spacefaring species that’s advanced enough to have planetary gravitational maps, of course mass is what we should be using. But also weight as force is just kinda funny to use outside the myriad times you actually need to in engineering

        Specifically LBS is a force, though. Imperial Pounds is not a mass measurement, so converting it would be a better equivalent to Kilonewtons.

      This has the energy of an 11 year old who just learned what weight is in physics

        Or a middle school physics teacher that barely knows what they’re talking about.

      Us customary defines the pound to be a unit of mass. Thats all you need to know.
