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 Gram (g)
A metric unit of mass equal to exactly 0.001 kg = 10⁻³ kg. The gram is the everyday working unit for: cooking and recipe measurements (international metric cookbooks; baker's percentages; pre-portioned ingredients), nutrition labels per Codex Alimentarius + EU Regulation 1169/2011 + FDA 21 CFR Part 101 (typical serving sizes 30-250 g; carbohydrates / protein / fat reported per serving in grams; total fat 'low' < 3 g, 'high' > 17.5 g per 100 g per UK Food Standards Agency traffic-light criteria), precious metals (a Tola = 11.66 g; jewelry gold-content quoted in grams), pharmaceutical compounding per USP <795> + EP (active pharmaceutical ingredient API mass in grams; typical excipient masses for tablets 10-500 mg), and analytical chemistry per ASTM E27 / E177 / E1402 (gravimetric analysis precision ±0.0001 g on analytical balance). Reference masses: a US 5-cent nickel is exactly 5.000 g (US Mint specification); a standard paperclip ~1 g; a US penny 2.5 g; a US quarter 5.670 g; a sheet of A4 80 gsm paper 5.0 g; a teaspoon of granulated sugar 4 g; a tablespoon of butter 14 g. International nutrition data is quoted per 100 g for cross-product comparability.
