What is 10.7 kg in Stone?
10.7 kg is equal to 1 stone and 8.4 pounds (or approximately 1st 8lbs). To convert kilograms to stone, divide the weight by 6.35029 — the standard conversion factor used across the UK. At this relatively light weight, BMI context depends on your height, but for most adults this would fall into the underweight or lower healthy weight range. Use our free weight converter above to check how this weight converts to other units, and our BMI calculator to see where you sit on the NHS health scale.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Kg to Stone Conversion Table
Here's a quick reference table showing 10.7 kg alongside nearby weights converted into stone and pounds:
- 8.7 kg = 1 stone 5.6 lbs
- 9.2 kg = 1 stone 6.9 lbs
- 9.7 kg = 1 stone 8.2 lbs
- 10.7 kg = 1 stone 8.4 lbs (your weight)
- 11.2 kg = 1 stone 10.1 lbs
- 11.7 kg = 1 stone 11.4 lbs
- 12.2 kg = 1 stone 12.7 lbs
The formula is simple: kg ÷ 6.35029 = stone. At 10.7 kg, this gives 1.685 stone — which converts to 1 stone and 8.4 pounds. For precise conversions between all weight units, use the interactive weight converter on this page.

10.7 Kg BMI & Healthy Weight Context
At 10.7 kg, your weight alone doesn't determine health — height matters significantly. For example, an adult who is 150 cm (4ft 11in) tall and weighs 10.7 kg would have a BMI of around 7.5, which is severely underweight. However, this weight might be healthy for a very young child. For adults, the NHS considers a healthy BMI between 18.5 and 24.9, typically requiring weights of 50+ kg depending on height. If you're concerned about being underweight, use our free BMI calculator above to check your personal BMI and discuss the result with your GP, especially if weight loss has been unintentional.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 10.7 kg to stone manually?
Divide 10.7 by 6.35029. The result is 1.685 stone. To convert the decimal (0.685) to pounds, multiply by 14: 0.685 × 14 = 9.59 pounds. So 10.7 kg ≈ 1 stone 8-9 pounds. For faster conversions, use our free weight converter tool on this page.
Is 10.7 kg a healthy weight for an adult?
At 10.7 kg, almost all adults would be severely underweight regardless of height. This weight is appropriate for infants or very young children, not adults. If you're an adult at this weight, speak with your GP urgently, as it may indicate an underlying health condition or nutritional deficiency requiring medical support.
What's the difference between stone and kilograms?
Stone is the traditional UK weight unit; kilograms are the metric standard used globally and by the NHS clinically. 1 stone equals 6.35029 kg. The UK commonly uses stone and pounds for body weight, whilst healthcare professionals often record weight in kg. Both units measure the same thing — it's just a matter of convention and preference.
Can I use this conversion for other weights?
Yes. The conversion formula (kg ÷ 6.35029 = stone) works for any weight. You can also use our free weight converter above to instantly convert any weight between kg, stone, and pounds. It's faster and removes the risk of calculation errors.
How does 10.7 kg compare to average UK adult weight?
The average UK adult woman weighs approximately 71.6 kg (11st 3lbs), and the average man weighs around 85.7 kg (13st 7lbs). At 10.7 kg, you'd be significantly lighter than any adult average — this weight is typical only for infants or very young children. If this applies to you as an adult, your GP should assess your health.
