Pounds are a measure of weight (force) not mass like grams. Stone is the imperial measure of mass and slug is the standard unit (US unit). In metric Newtons would be equivalent to pounds.
A pound at one gravity is equivalent to 2.2 kg at 1 gravity. Outside of aerospace there’s not really a need to distinguish between mass and weight so it kind of gets used interchangeably.
It just bothers me when people complain about units and then use the wrong kind of unit.
