Sorry, perhaps this is a disciplinary difference. In engineering, physics, and biomechanics (my doctoral specialization), and from a unit standard perspective, the pound representing both mass and weight is a false equivalency born out of convenience. This is why the Imperial standard for mass is the slug, allowing for gravitational acceleration of a mass to equate to a force.
Yeah this is exactly why I was confused. Pounds can definitely be used to measure mass. So the guy was wrong and assuming stupid parameters
Wait what? Even if you're measuring mass both times?
You're right, "pounds" is ambiguous.
Kilograms are mass, but pounds are weight. Therefore 0 kg = 0 slug, or 0 N = 0 lbs
I thought pounds could be used for either mass or force, and in modern usage just saying "pounds" usually refers to mass. Wikipedia seems to agree:
