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
LBS is Imperial Pounds which is a measure of Force and not Mass. That is why your LBS fluctuates based on gravity but your mass doesn’t. So they are correct.
Kilonewton? That would be a force and not a mass. For mass the standard unit is (kilo)grams.

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.

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

I see. Okay. Didn’t know that.
