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 Stones
A stone (st) equals 14 pounds or approximately 6.350 kg. It is the standard unit for expressing human body weight in the United Kingdom and Ireland, where a person will say they weigh '11 stone 4' (meaning 11 stone and 4 pounds, or 158 lb / 71.7 kg). Despite the UK's official adoption of the metric system, stones remain the dominant unit for personal body weight on British bathroom scales, in doctors' offices, and in everyday conversation. British newspapers and sports reports routinely describe athletes' weights in stones and pounds.
