Conversion of grams to stones and stones to grams is an easy one since both units are used for measuring mass. And while gram is a unit of the SI system of units, obviously the stone is not a unit of the SI system of units and is not used often anymore.
One stone (st) is a unit of mass defined as having exactly 14 pounds, while one pound (lb) is defined as having exactly 0.45359237 kg or 453.59237 grams.
Thus we can find the relation between gram (g) and stone (st):
M_{(stone)} = 14 Pounds = 14 * 0.45359237 kg = 6.35029318 kg = 6350.29318 g = ~6350.3 g
M_{(gram)} = M_{(stone)} / 6350.29318 = 0.00015747304 st
So, one stone equals ~6350.3 grams and one gram equals ~0.000157473 stones.
Stone (st) as a unit of mass is mostly used for measuring the weight of the human body (sports events, for example, boxing) and very rarely in trade.
Over time, different values for stone were used, but after standardization 1 (one) stone is 14 pounds (pounds are also standardized to 0.45359237 kg), making the conversion from stone to grams and grams to stones much easier.
