About Stone (st)
A British imperial unit of mass equal to exactly 14 pounds (= 6.35029318 kilograms per NIST SP 811). The stone is still the everyday unit for personal body weight in the United Kingdom and Ireland — colloquial usage routinely says 'I weigh 12 stone' rather than 168 pounds or 76 kilograms — and British bathroom scales typically display stones and pounds (e.g., '11 st 8 lb') as the primary scale alongside kilograms. Officially abolished from UK commerce in 1985 under the Weights and Measures Act amendments, the stone nonetheless remains cultural shorthand in British medical charts, GP consultations, fitness and weight-loss programs, and casual conversation about weight. Equine and livestock weights in Britain and Ireland are also still sometimes quoted in stones at agricultural auctions and equestrian weighing. Reference values: average UK adult male body weight ~12 st 5 lb (78 kg), average UK adult female ~11 st 2 lb (70 kg) per ONS Health Survey England. Convert stones to kg by multiplying by 6.350; to lb by multiplying by 14.
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 'troy pound' (used for precious metals) is different at 12 troy ounces = 373.24 g.
