Convert Kilograms to Stone
1 kilogram is 0.16 st. One kilogram is exactly 0.157473044418 stone.
One kilogram is 0.15747304 stone. To convert kilograms to stone, multiply by 0.15747304; to go the other way, divide by 0.15747304 or multiply by 6.3502932. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.

A stone is 6.35 kg, and it is a British unit only
Exactly 14 pounds, so 6.35029318 kg. UK medical records and bathroom scales use stones and pounds together; the US uses pounds alone and the rest of the world uses kilograms. A weight given as "11 st 4" is 11 × 6.35 + 4 × 0.4536 = 71.7 kg.

What is a kilogram?
The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.
What is a stone?
Fourteen pounds. Still the everyday unit of body weight in Britain and Ireland, and nowhere else.
How many stone are in a kilogram?
One kilogram is 0.15747304 stone. Going the other way, one stone is 6.3502932 kilograms. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
