How Silver Is Weighed

Pure silver metal is not as heavy as gold.  Silver has a density of 10.497 g/cm3, making a cubic foot of silver around 653 pounds.  Pure gold (24 karat) has a density of 19.282 g/cm3, which comes to 1,203.74 pounds for a cubic foot.  Like most precious metals and gemstones, silver is typically measured in troy ounces.  This unit of measure is used for buying and selling silver bullion, for establishing the price of silver, and is also used by governments worldwide.


A troy ounce (t.oz) is about 10% heavier than a regular ounce (1 t.oz = 1.0971428587 oz to be exact).  There are 12 troy ounces per troy pound.  In metric units, a t.oz is 31.1034768 grams.

Jewelry is usually weighed in grams. Sometimes, small amounts of silver are also expressed in grains.  A grain is 0.06479891 grams, as defined by the international yard and pound agreement of 1959.  A t.oz has 480 grains.

In the majority of the time, if one sees silver expressed in ounces only, one can assume that it is in troy ounces, but verification should be made.
