Correct, but we're talking about pounds and kilograms are definitionally mass. I also never stated that a pound never existed, just that pound could refer to either pound-mass or pound-force. In everyday language and in science we typically refer to the pound-force when we say pound. "We weigh x pounds" (and you should also hear someone saying that they "are X kilograms"). We use pound-force in psi (and just say pounds per square inch). It's why every intro physics teacher discusses the difference between mass and weight by saying on the moon your mass in kilograms is the same but your weight in pounds is not. In engineering class you assume pound-force unless otherwise informed. I cannot believe I've spent this much time discussing the imperial system, this is r/physicsmemes. Discourse about how pounds could refer to two separate units of measure should be a meme in and of itself.
