Hi All
   If I remember my physics, mass does not vary with location (unless you are traveling very fast) but force does ( f=m*a) . the earths acceleration does vary with location.

  the comparrison is deeply flawed.  A metric tonne is a unit of mass, a ton is a unit of force. Someone screwed up significantly when we went metric. It should have been Newtons or Kilo-Newtons for measuring weight.

  Hi Ian,
   
      No, it should not be defined as the force. If it were, the actual quantity (mass) would vary from place to place. The ton in commerce is also mass. Going metric wasn't a 'screw up'?
