How to convert kg to st
The stone (14 pounds, 6.35 kg) is still the everyday unit for reporting a person's weight in the UK and Ireland, even though both countries otherwise use metric units for almost everything else, a rare case of a pre-metric unit surviving specifically in casual speech rather than in any technical or commercial context.
Historically, "stone" referred to a range of local weight standards used for wool, cheese and other goods before being formally fixed at 14 pounds in the 19th century; the unit itself is named for literal stones once used as calibrated weights on balance scales, long before any standardisation existed. Ireland uses the stone alongside the UK for everyday weight, but neither country uses it in medicine, law or official statistics: hospital records and prescriptions are kept in kilograms.
