Mass can be thought of as the property of material that results in inertia, or the resistance to force. Weight and mass are never the same, although they may have the same numbers and the same units (added: lbm and lbf are really not the same). Weight is the "force" (quotes due to relativistic effects) resulting from gravitational acceleration acting on a mass F = mg where F is the weight and m is the mass.

Mass is the total ammount of matter (stuff) in an object and is measured in Kilograms.
it is NOT the same as weight, which is to do with gravity and is measured in newtons.

Expanding on the last answer. Mass is a unit of measure that quantifies matter.
In SI the common unit is the kilogram. In US Customary Units it is the slug.

Mass and weight are the same thing for a body at rest in a gravitational field. In free fall the body becomes weightless but its mass remains the same.

The amount of kilograms something is.
'8. Physics. the quantity of matter as determined from its weight or from Newton's second law of motion. Abbreviation: m Compare weight (def. 2), relativistic mass, rest mass.'
