How to convert kilograms to stones and pounds

If you are in the UK or comparing health data across countries, you may need to convert kilograms (kg) into stones and pounds (st and lb). One stone equals 14 pounds, and one kilogram equals approximately 2.20462 pounds. This means conversion is simple once you know the right steps.

Quick conversion formula

• Total pounds = kilograms × 2.20462
• Stones = floor(total pounds ÷ 14)
• Remaining pounds = total pounds − (stones × 14)

The calculator above performs these steps automatically and gives a clean result with decimal precision.

Why people use stones and pounds

Kilograms are part of the metric system and are standard in most of the world. Stones and pounds are still common for body weight in the UK and Ireland. If you are reading fitness plans, medical reports, or weight-loss milestones from different regions, converting units helps avoid confusion.

For example, someone may say they weigh “11 stone 4 pounds” rather than “71.7 kilograms.” Both are correct, just different systems.
