A material's density is the measure of its weight for a given volume.

  The Karat Gold Density Table lists the densities of Handy & Harman gold alloys, in full karats. To determine the weight difference between equal volumes of different karat gold alloys, calculate the ratio of their respective densities.

  For example, to convert from 100 dwts. of 10 karat

Satin Yellow Gold to 14 karat Satin Yellow Gold, the weight equivalent in 14 karat would be figured as follows:

 

100 dwts. of 10K 6.76

Satin Yellow Gold 6.11

 

(density of 14K)

(density of 10K)   

 

           =

 

110.64 dwts. of 14K

Satin Yellow Gold

 

An extra 10.64 dwts. of 14 karat Satin Yellow Gold

would be needed to fill the same volume filled by 100

dwts. of 10 karat Satin Yellow Gold.

  This calculation can be used for the conversion of

any alloy to another to determine weight per volume.
