When you'll use this
- Converting a kg-based bathroom scale reading into the stone format still commonly used and understood in the UK
- Checking a metric BMI or NHS health chart figure (kg) against the stone-based weight most British people grew up estimating in
- Converting an international fitness app's kg weight log into stone for a UK user

Practical note
Most UK healthcare and fitness data is now recorded in kilograms, but stone remains the unit most British people actually think in day to day — this page is the bridge between the two. A metric fitness app showing "82 kg" converts to about 12.9 stone (roughly 12 stone 12 lb), a figure that is much easier for a British user to place intuitively than the raw kilogram number. It is also useful for reading UK news and sports coverage, where body weight is still sometimes reported in stone even when the underlying data was collected in kg by a hospital or sports science team.
Tips
- 1 kg is about 0.157 stone — a useful mental shortcut is dividing kg by 6.35 for a quick estimate before checking the exact figure.
- The UK NHS and most British GPs now record weight primarily in kg, but many British people still think and talk about their weight in stone — this page bridges the two.
- Results convert cleanly to "stone and pounds" format by taking the whole-number part as stone and multiplying the remaining decimal by 14 for the pound remainder.
