107 kg in Stones and Pounds — BMI Guide
107 kilograms is equivalent to 16 stone 12 pounds (16st 12lbs). However, whether this weight is healthy for you depends entirely on your height.

Use our free BMI calculator above to find your exact BMI, then check where you fall on the NHS weight categories. This guide shows you what 107kg means for your health at different heights.

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.
What's Your BMI at 107 kg? Examples at Different Heights
To understand your health at 107kg, you need to know your height. Here are realistic examples of BMI at this weight across common UK heights:
- 160 cm (5ft 3in): BMI ≈ 41.6 — Severely obese (Class III)
- 165 cm (5ft 5in): BMI ≈ 39.3 — Obese (Class II)
- 170 cm (5ft 7in): BMI ≈ 37.1 — Obese (Class II)
- 175 cm (5ft 9in): BMI ≈ 34.9 — Obese (Class I)
- 180 cm (5ft 11in): BMI ≈ 32.9 — Obese (Class I)
- 185 cm (6ft 1in): BMI ≈ 31.3 — Obese (Class I)
These are approximate values — use the metric to imperial weight converter and BMI calculator on this page for your exact measurements. Your GP can give you personalised advice about what your BMI means for your individual health.

NHS BMI Categories and What They Mean
The NHS classifies BMI into clear categories. A BMI below 18.5 is underweight, 18.5–24.9 is healthy, 25–29.9 is overweight, 30–34.9 is obese (Class I), 35–39.9 is obese (Class II), and 40+ is severely obese (Class III). At 107kg, most heights fall into the obese category, which increases risk of type 2 diabetes, heart disease, and other weight-related conditions.
Remember: BMI has limitations — it doesn't account for muscle mass, bone density, or where fat is stored. Track your progress using our free progress tracker, and always consult your GP for personalised weight and health advice.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I convert 107 kg to stones and pounds?
Divide 107 by 6.35 to get approximately 16.85 stone. To express this as stones and pounds, multiply 0.85 by 14 to get approximately 12 pounds. So 107 kg = 16 stone 12 pounds. Use our free weight converter above to confirm exact conversions instantly.
What BMI is 107 kg?
Your BMI at 107kg depends on your height. At 170cm (5ft 7in), BMI is approximately 37.1 (obese). At 180cm (5ft 11in), it's approximately 32.9 (obese). Use our free BMI calculator at the top of this page to find your exact BMI by entering your height.
Is 107 kg overweight according to the NHS?
At 107kg, most adults fall into the obese category according to NHS guidelines, regardless of whether they're male or female. This is because obesity is determined by BMI, which combines weight and height. Your GP can discuss what this means for your individual health.
What is the healthy weight range at my height if I weigh 107 kg?
The healthy weight range depends on your height. At 170cm, healthy weight is roughly 53–71kg. At 180cm, it's roughly 60–80kg. Calculate your personal healthy weight range using our free BMI calculator, which shows the exact range for your height.
Can BMI alone tell me if my health is at risk?
BMI is a useful screening tool but has limitations — it doesn't distinguish muscle from fat or account for where fat is stored. Your waist circumference and overall fitness also matter. Always speak to your GP about your personal health risk, especially if you have existing health conditions.
