About Stone and Gram
The stone equals 14 pounds, exactly 6.35029318 kilograms. It survives almost exclusively for stating body weight in the UK and Ireland. The gram is one thousandth of a kilogram. Recipes, nutrition labels, and postal scales work in grams because the kilogram is too coarse for them. One Stone equals 6350.29318 Grams (1 st = 6350.29318 g). Stone is used in body weight in the UK and Ireland and in boxing and horse racing weight classes. Gram is used in cooking and baking recipes.
Precision and Rounding:Metric-imperial mass factors are exact (1 lb = 0.45359237 kg by the 1959 agreement), so precision is purely a display choice. One decimal place is enough for body weight and cooking; nutrition labeling, pharmacy, and lab work need the full factor before rounding.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
