Stone to Kilogram and pound convertor

If you grew up in the UK, chances are you measure body weight in stones and pounds. But the rest of the world? Kilograms. And sometimes, even pounds on their own. That mix of systems can get confusing — which is exactly why we built this Stone to Kilogram and Pound Converter.

Why Stones Are Still Popular in the UK

Ask someone in London their weight and you’ll probably hear “12 stone” before you hear “76 kilos.” Stones have been part of everyday language for decades, and many of us still think in that format.

The tricky bit comes when you need to switch: your gym equipment, airline luggage, or international medical forms will often ask for kilograms instead. That’s where a converter saves you the hassle.

How the Conversion Works

Here are the basics:

• 1 stone (st) = 6.35029 kilograms (kg)

• 1 stone = 14 pounds (lb)

• 1 kilogram (kg) = 2.20462 pounds (lb)

So if you type a number of stones into our tool, you’ll instantly see it in both kilograms and pounds.

Quick Examples

• 8 stone = 50.8 kg = 112 lb

• 10 stone = 63.5 kg = 140 lb

• 12 stone = 76.2 kg = 168 lb

• 14 stone = 88.9 kg = 196 lb

This is especially useful if you’re switching between health trackers, fitness apps, or even comparing luggage allowances before a holiday.

Other Handy Conversions

Our site also covers the opposite situations too:

• Need to check stone to pound directly? We’ve got you covered.

• Prefer to see the reverse, like pound to stone? Use our converter the other way round.

• Want to stick with metric? Use Kg to Stone(st)to keep things simple and consistent.

Why Use a Converter Instead of Guesswork?

Yes, you can do the maths yourself (multiply stones by 6.35 for kilograms or by 14 for pounds). But let’s be honest — who wants to fumble through decimal places every time? Our converter gives you:

• Instant accuracy

• No mental maths

• Clear results in all three units

It’s faster, cleaner, and avoids silly mistakes.

Final Word

Whether you’re weighing yourself, logging progress at the gym, or double-checking baggage weight for a trip abroad, the Stone to Kilogram and Pound Converter is a simple way to see all three units side by side.

Stones may be traditional, but in a global world, it pays to know the kilos and pounds too. With this tool, you don’t have to choose — you’ll always have the numbers ready.
