Number of Karats in Pure Gold

How many karats are there in pure gold?

24.

The term karat (or carat) was coined to designate the quantity of gold in gold alloys. A 24-karat piece is made of 99.9% gold (which is considered pure gold), whereas in 18-karat there is 75% gold, and 50% in 12-karat. Another way of measuring gold purity is through the millesimal fineness, with values of decimal figures from 0 to 1, where 999 (or three nines fine) means pure gold.
