- masklinn 10y ago> This is incorrect. The pound is a unit of force, similar to a Newton. The pound-mass(notated lb-m) is similar to the kg. That's the pound-force (lbf). Pound and pound-mass are aliases. Indeed the official facts sheet defines the mass of the rover in kg and pounds. > The conversation you gave above is based on Earth gravity for weight. My comment is based on mass being an intrinsic property of matter, gravity does not enter the equation.
