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.
107kg to Stone Conversion Table
To convert 107 kilograms to stone using the standard kg to stone conversion formula, divide the kilogram value by 6.35029. This gives you 16.86 stone, which breaks down to 16 stone and 12.8 pounds. Below is a conversion table showing nearby values so you can see how 107kg compares:
- 102 kg = 16 stone 1.7 lbs
- 104 kg = 16 stone 6.2 lbs
- 106 kg = 16 stone 10.7 lbs
- 107 kg = 16 stone 12.8 lbs
- 108 kg = 17 stone 0.9 lbs
- 109 kg = 17 stone 3 lbs
- 110 kg = 17 stone 5.1 lbs
Whether you prefer weight in stone or kilograms, both units are equally valid — stone remains the traditional UK measurement for body weight in everyday conversation, whilst kilograms are used in clinical settings.

107kg BMI and Healthy Weight Context
At 107 kg, your BMI depends entirely on your height. For an average UK adult woman (5ft 4in / 163cm), 107kg gives a BMI of approximately 40, which falls into the severely obese category. For an average UK adult man (5ft 9in / 175cm), the same weight gives a BMI of around 34, which is obese. A healthy weight range at these heights would be significantly lower — use our free BMI calculator above to check your personal BMI and see what healthy weight range applies to your specific height. Even a modest weight loss of 5–10% of body weight can bring meaningful health improvements.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 107kg to stone and pounds?
Divide 107 by 6.35029 to get stone (16.86 stone). Multiply the decimal (0.86) by 14 to get pounds (12.04 lbs). So 107kg = 16 stone 12.8 lbs. Our free weight converter above does this instantly.
Is 107 kilos a healthy weight?
It depends on your height. At average UK heights, 107kg typically falls into the obese category. Your GP or a BMI calculator can tell you if this weight is healthy for you personally. Healthy weight ranges vary significantly by height and build.
What's a healthy weight range if I'm 107kg now?
This depends entirely on your height. For someone 5ft 9in tall, healthy weight is roughly 65–82kg. For 5ft 4in, it's about 50–67kg. Use our BMI calculator to find your personal healthy range based on your exact height.
Can I use a standard converter for kg to stone conversion?
Yes — the formula is simple: divide kilograms by 6.35029. However, our free weight converter above does this automatically and instantly, plus shows you nearby values for easy reference.
Should I be concerned if I weigh 107kg?
Not necessarily on its own — weight alone doesn't determine health. Your GP can assess your overall health, including blood pressure, blood sugar, fitness, and family history. If you have health concerns, speak to your GP for personalised advice.
