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 UK long ton (symbol L/T, also "imperial ton" or "gross ton") equals 2,240 avoirdupois pounds or 1,016.0469088 kilograms. Used in Britain for coal and shipping, it is slightly larger than both the US short ton (2,000 lb) and the metric ton (1,000 kg). Britain adopted metric units in 1965 and the long ton is no longer used in new UK trade contracts, though it appears in historical records.
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 long ton traces to medieval England, where a "wine tun" was a large barrel of ~252 gallons. A standard ship's cargo unit ("ton burden") evolved into a 2,240-pound standard because 2,240 lb = 20 hundredweight (each of 112 lb) — convenient for counting by the hundredweight. The Coal Industry Act 1831 formalised the long ton for coal. British Overseas Territories and some US steel industry sectors still use it.
Interesting fact: HMS Victory, Nelson's flagship at Trafalgar (1805), was rated at 2,162 long tons displacement. Modern international shipping uses metric tons (deadweight tonnage), but engineers working with pre-1965 British specifications regularly need long ton conversions.
