Pounds to Carats

Pound

A pound (lb) is a widely used unit of weight in the United States and parts of the United Kingdom. It equals 16 ounces or about 0.4536 kilograms. Pounds are a familiar measurement for body weight, groceries, luggage, and many everyday objects. Because pounds are part of the US customary system, converting to metric units often requires exact factors rather than simple scaling.

The pound remains a common standard in fitness, cooking, and retail packaging. When comparing product weights internationally, a converter ensures that pounds translate clearly into kilograms or grams.

Carat

A carat (ct) is a specialized metric unit used to measure gemstones and pearls. One carat equals 200 milligrams — or 0.2 grams — making it perfectly sized for tiny but valuable items. Jewelers and gemologists rely on carats because small weight differences can significantly affect a stone’s price and quality.

Carats provide precision without using long decimal values in grams or milligrams. However, when converting gemstone weights to more common units, exact conversion factors are necessary — and this is where a converter becomes helpful.
