What is a Stone to Kilogram Converter?

This converter allows you to convert between stones (st) and kilograms (kg). The stone is a unit of mass commonly used in the United Kingdom and Ireland. One stone equals 6.35029318 kilograms. The need for such a converter arises from the fact that many people still measure their weight in stones and find it helpful to have a quick way to see that weight in kilograms, especially when using metrics for fitness or medical purposes.

Enter a value and select the unit you are converting from. The converter will automatically calculate the converted value in the selected target unit, making weight management and understanding much simpler.

How the Conversion Works

Conversions are done via a base unit: kilograms. First, the input is converted to kilograms; then, it is converted to the desired target unit. This two-step approach ensures consistent and accurate results, allowing users to trust the output of the calculator.

Result = (Value × From Unit Factor) / To Unit Factor

For this tool, the factors are:

  • 1 stone = 6.35029318 kilograms
  • 1 kilogram = 1 kilogram (base)

Understanding these factors is crucial for ensuring that the conversions you make are both accurate and reliable.
