True, but WaxProlix is correct. Ten kilograms is 22 pounds on Earth, but 2.2 trillion pounds on the given Neutron Star.



I was going to jump in and say that the pound is also a unit of mass. But it turns out its both.

And then there's the foot-pound, a unit of torque much prized by the owners of muscle cars until eclectric vehicles went from obscure to early-adopter status.


Or just general torque in the United States. Electric vehicles still have tires that are joined to wheels which are fastened to an axle by the tightening of a nut on a threaded stud. For safety, we generally state that the nut should have X foot-pounds of torque applied to ensure it doesn't fall off. Unless Tesla et al. have suddenly decided to use a more universal standard in the states, I'd assume they still publish that value in ft/lbs, since 98% of tools designed to measure these things owned in the U.S.A. have this unit on them.


Also, assuming we're talking about rest mass, since without that distinction the word mass is ambiguous in accelerated contexts.
