Kilograms to Stone Converter
Converting kilograms to stone is a multiplication by a fixed factor: 1 kg = 0.157473 st. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.
Because one kilogram works out to 0.157473 st, the stone is the much smaller unit of the two: a figure given in stone always carries a smaller number than the same measurement in kilogram. A chart drawn in kg can hide that, so check which label the axis uses before you compare two readings.
Where a legal or postal limit is set in stone, the same limit expressed in kilograms has to be exact — an overshoot of even one unit can change the chargeable band.
The conversion factor used here is 0.157473 st per kilogram (6 significant digits as shown). Kept to seven figures it covers professional measurement; if you round it to two or three decimals for a spreadsheet, the error scales with the input — at a value of 1,000 kg a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 6.350293 kg per st, the exact reciprocal, so a round trip through both pages returns your original number.
