Convert Pound to Hundredweight (US)

The pound has its origins in ancient Rome, where it was known as the libra, a unit of weight equivalent to around 327 grams. The term pound comes from the Latin word "libra", which was used to refer to both the Roman pound and the unit of weight for trade. Over time, the pound evolved through various forms, including the Avoirdupois pound used in medieval England, which was based on a system of 16 ounces. The Avoirdupois pound became the standard for most goods in the U.S. and Britain by the 14th century and was later standardized internationally, with its value fixed to the kilogram in the 20th century.

The hundredweight originated in medieval England as a unit of mass for measuring grain and other agricultural products. It was defined as 100 pounds. The term "hundredweight" comes from the Latin word "centum", meaning "hundred". The hundredweight was used in trade and agriculture for centuries and was adopted in the United States as part of the U.S. customary system.
