A karat is a measure of purity, not weight when it comes to gold. A piece of jewelry with 1 karat gold would be 1/24th gold by weight.
Karat (K) is the number of parts, by weight, of gold. The higher the percentage of pure gold, the higher the karat. For e.g., 14 karat gold is 58% gold, 18 karat gold is 75% gold and 24k gold is pure. 22k gold is 91.67% gold.
