ConvBolt — Unit ConverterStone to Grams Converter
Converting stone to grams is a multiplication by a fixed factor: 1 st = 6350.293 g. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.
Because one stone works out to 6350.293 g, the gram is the much larger unit of the two: a figure given in gram always carries a larger number than the same measurement in stone. A chart drawn in st can hide that, so check which label the axis uses before you compare two readings.
Where a legal or postal limit is set in grams, the same limit expressed in stone has to be exact — an overshoot of even one unit can change the chargeable band.
The conversion factor used here is 6350.293 g per stone (3 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 st a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 0.000157473 st per g, the exact reciprocal, so a round trip through both pages returns your original number.
