The term stone is used in Great Britain to describe the weight of a person or animal. Like many units, the stone often varied in actual weight until it was standardised at 6.35 Kilogram, according to the University of North Carolina. When used as a unit, the term "stone" is used even when discussing the plural. Kilograms are a unit used around the world to quantify mass. You can use conversion factors to convert from kilograms to stone.
Determine the number of kilograms you want to convert to stone.
Multiply the number of kilograms by 2.2 to convert to pounds. For example, if you want to convert 50 kilograms, you would multiply 50 by 2.2 to get 49.9 Kilogram.
Divide the number of pounds by 14 to convert the weight to stone. Finishing the example, you would divide 110 by 14 to find that 50 kilograms equals about 7.86 stone.
