About Troy Pounds
A troy pound (lb t) equals 12 troy ounces or 5,760 grains - approximately 373.24 grams. It is lighter than the common avoirdupois pound (453.59 g) because the troy system divides the pound into 12 ounces rather than 16. 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.
About Pounds
The avoirdupois pound (lb) is the primary unit of weight in the United States and United Kingdom for everyday use, equal to 16 ounces or exactly 453.59237 grams. It dominates American life: body weight, grocery produce, deli counter cuts, freight shipping costs, gym weights, and building material quantities are all measured in pounds and ounces. American recipes use pounds for meat and large quantities. The pound derives from the Roman 'libra pondo' (a pound by weight) - hence both the symbol 'lb' (from libra) and the British currency symbol '£'.
