Determining Weights of Metals and
Alloys
The
specific gravity of a metal or alloy is merely the weight in grams of one cubic
centimeter. When it is more convenient to work in troy weights the number of
ounces per cubic inch of any metal or alloy may be found by multiplying its
specific gravity by the constant .52686. For example, the specific gravity of
14K yellow gold is 13.07. This multiplied by .52686=6.88606 which is its weight
in troy ounces per cubic inch.
