Why People Convert
Kilograms are the standard unit on most medical scales and fitness equipment in the UK, but stone remains the unit most British adults think in for body weight. If your GP record or gym scale shows kilograms and you want to understand your weight in stone, this converter gives you the exact figure. UK residents receiving American health documents or using US-based fitness apps often see pounds instead — the pounds column in the reference table below covers that too.
The Conversion Formula
kg ÷ 6.35029318 = stone (decimal)
Decimal remainder × 14 = pounds
Example: 75 kg ÷ 6.35029318 = 11.81 stone = 11 stone 11 pounds
The kg-to-stone conversion comes up regularly in clinical practice because many patients track their weight in stone at home but arrive at appointments where everything is recorded in kilograms. The numbers can feel confusing — 80 kg sounds heavier than 12 stone 8 pounds even though they are the same weight. I always make sure patients understand what their kg figure means in the units they are familiar with, because weight management is much harder when the numbers feel abstract. If you are using this page to understand a weight given to you by a clinician, the reference table below and the BMI section further down will help you put it in context.
