1 ct ≈ 3.08647167059 gr
1 gr = 0.32399455 ct
Formula: gr ≈ ct × 3.08647167059
ct = gr × 0.32399455
Definitions: 1 ct = 0.2 g; 1 gr = 1/7000 lb
The metric carat (ct) is exactly 200 milligrams and is the unit for weighing gemstones such as diamonds. It should not be confused with the karat, which measures the purity of gold.
The grain (gr) is exactly 64.79891 milligrams and is the base of the avoirdupois, troy and apothecaries weight systems, originally based on a grain of barley. It is used today mostly for the weight of bullets and powder charges in ammunition.
