One Troy ounce of gold weighs 31.1035 grams.
One ounce of gold is accepted
to mean 31.1 grams of pure 24 carat gold although in reality it is likely
to be 0.9999% pure, often called four nines.
Imperial ounces, equivalent
to 28 grams, are not used.
A carat is both a unit of weight and also an indication of fineness, that
is, a value for the percentage of pure gold content. 24 carat gold represents
100% gold with no alloy content.
A one ounce, 1 (Troy) ounce, 9ct gold bracelet weighs 31.1gms.
Actual gold content is (9/24)*31.1=11.66gms of pure (24ct) gold. This also
means that (31.10-11.66) 19.44 gms in every troy ounce are other alloys.
These alloys, like silver and copper, give rise to the qualities of the metal
such as colour and hardness.
