To find the weight of an article in a metal different from that in which it is now made:

  1. Find the present metal in the first vertical column.
  2. Multiply the present weight by the factor in the same horizontal row under the new metal. Example: A sterling silver ring weighs 8 grams, what will it weigh in 14kt.
  3. Along the horizontal row marked Stg in the first column under the heading 14 Kt we find 1.25 x 8 = 10 grams, weight in 14 Kt.
