6 stone is 38.10 kilograms. The exact figure is 38.1017 kg, found by multiplying 6 by 6.35029. It is also equal to 84 pounds. This conversion is most commonly searched by parents tracking a child’s weight, by people monitoring recovery from illness or an eating disorder, and by individuals checking historical weight records that were recorded in stones.
At 6 stone, an adult at any height would be severely underweight. The NHS underweight threshold at the shortest commonly measured adult height of 4ft 10in corresponds to a weight of around 40 kg, which is still above 6 stone. For children, 6 stone is within the normal range for a child of around 8 to 10 years old at average height. As always with children’s weight, age-specific NHS growth charts are the correct reference rather than adult BMI values.

In clinical practice, seeing an adult patient at 6 stone would prompt an urgent assessment. The questions I would want to answer are whether the low weight is constitutional, which is rare but possible, or whether it reflects illness, nutritional deficiency, or an eating disorder. In my experience, most adults searching for this conversion at this weight already have some awareness that their weight is concerning them. That awareness is a starting point. A GP conversation, while it may feel daunting, opens the door to support that can make a real difference.
