The pound (lb) is the primary unit of mass in the US customary and British imperial systems, equal to exactly 453.59237 grams since the International Yard and Pound Agreement of 1959. It is subdivided into 16 ounces. The abbreviation "lb" comes from the Latin libra (scales/balance), while "pound" derives from Latin pondus (weight).
The US short ton (commonly just "ton" in American usage) equals exactly 2,000 avoirdupois pounds or approximately 907.18474 kilograms. It is the standard bulk commodity unit for coal, steel, cement, and freight in the United States. The "short" qualifier distinguishes it from the UK long ton (2,240 lb) and metric ton (1,000 kg).
The pound traces its origins to ancient Rome's libra pondo (pound weight, ~329 g). Various standards existed in medieval Europe — Troy, Tower, and merchant pounds — until the avoirdupois pound emerged in 13th–14th century England for general trade. The British Weights and Measures Act 1878 formalised it. The modern definition (453.59237 g) was fixed by the US, UK, Australia, Canada, New Zealand, and South Africa in 1959.
Interesting fact: The word "pound sterling" originally meant one pound (12 troy ounces) of sterling silver. Today's British pound currency takes its name from the unit of mass, not the other way around.
The short ton emerged in the United States as commerce adopted 2,000 pounds as a round-number bulk standard, diverging from the British 2,240-lb long ton. It was codified in the US Customary system in the 19th century. US coal production, steel output, and grain yields are still reported in short tons domestically, though international trade uses metric tons. The US is one of only three countries (with Myanmar and Liberia) not officially on the metric system.
Interesting fact: A fully loaded standard US freight car carries approximately 100 short tons of cargo. The US historically produced ~1 billion short tons of coal per year; modern US coal consumption has fallen to about 400–500 million short tons annually.
