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 metric ton (tonne, symbol t) equals exactly 1,000 kilograms or 1,000,000 grams. Not an SI unit but derived from the kilogram, it is used globally for large-scale measurements in shipping, agriculture, mining, and manufacturing. In the US, "metric ton" or "tonne" distinguishes it from the US short ton (2,000 lb ≈ 907 kg) and UK long ton (2,240 lb ≈ 1,016 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 tonne was introduced alongside the metric system in late 18th-century France and incorporated into the International System as an accepted non-SI unit. Its name (with final "e") was adopted to avoid confusion with British and American ton units. As international trade standardised on metric units through the 20th century, the metric ton became the global benchmark for commodity markets in grain, oil, steel, and other bulk goods.
Interesting fact: A standard ISO shipping container (20-foot TEU) can carry approximately 21–24 metric tons of cargo. The global annual steel production is about 1.9 billion metric tons — roughly 240 kg for every person on Earth.
