First of all, it is spelled Karat. Gold purity indication, especially in the US, is in Karats.
Carat is used as a measure of weight, for diamonds & gemstones, where 1 carat = 200 milligrams (5 carats=1 gram).
Karat refers to part of gold present per 24, where 24 is 100%.
So if you have 18k, it means 18/24 = 75% pure gold.
22k = 22/24 = 91.66%
The balance of 8.44% usually contains mainly Copper & Silver. Other metals in small quantities , which may or not be present are usually Zinc, cadmium, indium, irridium (since it is not affected by Nitric Acid, Irridium is used to cheat people in terms of purity).
Various other metals may be added to achieve required properties like ductility, malleability, hardness, toughness, colour shades, etc.
