Mass is commonly measured in ,kilograms,. If you put a ,kilogram, of material on the surface of the Earth, the pull of gravity will be a ,force, of 2.2 lbs. So a good definition of a ,kilogram, is an amount of material that weighs 2.2 lbs when placed on the surface of the Earth. That number is worth remembering.1 Go to the surface of Jupiter, and you will
