A troy pound (lb t) equals 12 troy ounces or 5,760 grains - approximately 373.24 grams.

Historically used across Europe for trade in precious metals and pharmaceuticals, the troy pound was the legal standard in England from the 15th century until 1878. In the United States, the troy pound was once the official standard for coinage but was abolished for commercial use in 1828.
