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.
I came here to say this. A chunk of mass that "weighs" 100 grams is still 100 grams on the moon. A chunk of mass that weighs 1 pound does not weigh 1 pound on the moon.
