Anna wants to buy a one carat diamond. One carat equals 200 mg. If a diamond is 0.600 carat, what is the mass of the diamond in ounces?

1 kg=2.205 pounds

1 pound=16 ounces

The mass of the diamond is 7.056 * 10⁻³ oz.

No. of grams = 1 ct * (200 mg/1 ct) * (1 g/1000 mg) = 0.2 g

No. of pounds = 0.2 g * (1 kg/1000 g) * (2.205 lb/1 kg) = 4.410 * 10⁻⁴ lb

No. of ounces = 4.410 * 10⁻⁴ lb * (16 oz/1 lb) = 7.056 * 10⁻³ oz
