How to read the chart
In the UK and Ireland body weight is still commonly given in stone and pounds, for example “11 stone 4”, where the second number is extra pounds and not a fraction. Most scales, health records and sports weigh-ins elsewhere use kilograms, which is why a stone to kg chart is handy for forms, medical appointments, travel and fitness apps.
The columns step up one pound at a time, so each cell is 0.45 kg higher than the one to its left. Reaching the end of the row (+13 lb) is one pound short of the next full stone.
The formula
kg = (stone × 14 + pounds) × 0.45359237
Worked example, 11 st 4 lb: 11 × 14 = 154 lb, plus 4 lb = 158 lb. 158 × 0.45359237 = 71.67 kg. To go back, divide kilograms by 0.45359237 for pounds, then divide by 14: the whole number is the stone and the remainder is the pounds. The kg to stone and pounds chart does that direction for every kilogram from 40 to 150.
