However, gold purity, sometimes referred to as gold fineness, is measured in karats (k).
Pure gold is 24 karats (24k). Due to the softness of pure gold, it is often mixed with other metals to create a gold alloy when creating jewelry pieces. This gives them a higher level of resilience to withstand everyday use. This app helps you to find gold fineness using two different methods.

The amount of gold in the alloy is given as the number of twenty-fourths. For example, gold jewelry made from 18k gold contains 18/24 gold (this equates to 75%). This app will find the percentage of impurity in the alloy.
