ConvBolt — Unit ConverterUS tons to Stone Converter
Converting US tons to stone is a multiplication by a fixed factor: 1 ton = 142.8571 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 us ton works out to 142.8571 st, the stone is the far larger unit of the two: a figure given in stone always carries a larger number than the same measurement in us ton. A chart drawn in ton can hide that, so check which label the axis uses before you compare two readings.
Cooking and shipping are the two places this pair appears most: a kitchen scale reads in US tons while a recipe or label is written in stone, and a courier tariff built on stone still has to be checked against a scale showing US tons.
The conversion factor used here is 142.8571 st per us ton (4 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 ton a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 0.007 ton per st, the exact reciprocal, so a round trip through both pages returns your original number.
