Conversion Formula

lb  = stone × 14  (exact — 1 stone = 14 lb by definition)
kg  = stone × 6.35029

For combined 'X stone Y pounds' values:
  total lb = (X × 14) + Y
  Example: 11 st 7 lb = (11 × 14) + 7 = 161 lb = 73.03 kg

   8 st  = 112 lb = 50.8 kg
  10 st  = 140 lb = 63.5 kg
  11 st  = 154 lb = 69.9 kg
  12 st  = 168 lb = 76.2 kg
  14 st  = 196 lb = 88.9 kg

Half-stone increments (add 7 lb = 3.175 kg per half stone)
Reverse: total lb ÷ 14 → quotient = stone, remainder = extra lb
