Weight/Talk

This page is basically a long argument that the historically correct usage of weight is mass. But the origins of words do not determine their proper use, and anyways, weight was first coined back when people didn't have any concept of the distinction between mass and force due to gravity. I've removed the bit about scales, since it is the least sensical - scales measure force due to gravity in circumstances where it will ideally be proportional to mass, so to claim they are truly measures of one or the other seems kind of absurd. The rest could stand some editing, though. The distinction between pounds and pound-forces is not supported by older physics texts, which usually use pounds as forces and slugs for mass, while acknowledging a different system where pounds are masses and poundals are forces.
