Calculating the Karat from the Millesimal Value
by: Anonymous

Hi Ruth, 18K or 750 (parts per 1000) is 75% gold. Most quality pieces are 18K. It is the minimum gold standard for sale in Italy.

Occasionally you find odd numbers. The odd numbers can easily be calculated using following equation:

1 karat gold is 1 part in 24 gold. As an example, 22K is 22 parts in 24 of pure gold or 22/24ths or if you multiply 22/24 X 1000 you get 916 (916 parts per 1000) or 91.6% gold.

Providing it is gold alloy, if you see a number, for example 700, divide it by 1000 and then multiply by 24, it will give you the carat. ie. 700 / 1000 x 24 = 16.8 K

best wishes
