About Pound (lb)
An imperial unit of mass equal to exactly 16 avoirdupois ounces = 0.45359237 kg (defined by the 1959 International Yard and Pound Agreement; the abbreviation 'lb' comes from Latin 'libra pondo' — 'pound by weight'). The avoirdupois pound is dominant in: US body weight (CDC NHANES data: US adult male mean 199 lb, female mean 170 lb 2017-2020 cycle), US grocery and produce pricing per FDA 21 CFR 101.105 + USDA Agricultural Marketing Service ('per lb' tags on meat, vegetables, bulk foods; typical retail meat $5-20/lb), US barbell plates per IPF + USAPL + NSCA strength training (Olympic plates 2.5/5/10/25/35/45 lb standard; world deadlift record ~1,100 lb; competition powerlifting weight classes 132/148/165/181/198/220/242 lb), US aviation aircraft weights per FAR Part 25 + Part 121 (max ramp + takeoff + landing + zero-fuel weights all reported in lb; Boeing 737-MAX MTOW 181,200 lb; Airbus A320neo MTOW 174,200 lb), US ammunition + bullet weights (bullet mass in grains; 7000 grains = 1 lb; .308 Win 168 gr = 0.024 lb), and US shipping rates per UPS + FedEx + USPS rate sheets (commercial freight ratings in lb).

The metric ton — also called 'tonne' in international English (the official BIPM SI Brochure spelling) — is the global commodity unit for bulk shipping per IMO + ICAO, industrial manufacturing per ISO 9001 + ISO 14001 production reporting, agricultural yield (USDA WASDE reports global crop production in million metric tons: 2024 global wheat ~790 Mt, corn 1,200 Mt, soybeans 410 Mt, rice 530 Mt, palm oil 80 Mt; FAO reporting in Mt or kt), steel production (worldsteel.org global crude steel ~1,900 Mt/year, China ~1,020 Mt, India 140 Mt, Japan 87 Mt, USA 80 Mt), and CO₂ emissions reporting per IPCC AR6 + UNFCCC + Carbon Brief / Our World in Data (global anthropogenic 37 Gt CO₂/yr = 37,000 Mt; per-capita US ~16 t/yr, China 8.3 t, EU 6.5 t, India 1.9 t per 2023 data; airliner round-trip NYC-LON 1.6 t CO₂ per passenger). Reference values: a typical 40 ft shipping container max gross 30 t; loaded Class-8 semi-truck 36 t US (80,000 lb GVW); standard passenger car curb weight 1.0-2.5 t; Saturn V rocket fully fueled 2,970 t.
