st = g × 0.000157473The stone is a British unit of weight, traditionally used for body weight. One stone equals 14 pounds or about 6.35 kilograms (6350 grams). Since most modern body weight is tracked in kg or lbs, converting grams to stone is uncommon — you'd only do it when working with historical UK weight records, antique scales, or certain UK medical forms that still use stone.
