   1. the quality of being heavy; that property of bodies by
      which they tend toward the center of the earth; the effect
      of gravitative force, especially when expressed in certain
      units or standards, as pounds, grams, etc.

   note: weight differs from gravity in being the effect of
         gravity, or the downward pressure of a body under the
         influence of gravity; hence, it constitutes a measure
         of the force of gravity, and being the resultant of all
         the forces exerted by gravity upon the different
         particles of the body, it is proportional to the
         quantity of matter in the body.

   2. the quantity of heaviness; comparative tendency to the
      center of the earth; the quantity of matter as estimated
      by the balance, or expressed numerically with reference to
      some standard unit; as, a mass of stone having the weight
      of five hundred pounds.
