I did a Google search for stone as a unit of measurement. Almost all references quoted 1 stone = 14 pounds, except one referred to a 'butcher's stone' weighing 8 pounds, so I'll go with the 14 pounds.
13 stones * ( 14 pounds/stone) = 182 pounds.
182 pounds * (0.4536 kg / pound) = 82.5552 kg
5 stone = 31.8 kilograms
