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.

BMI and Healthy Weight Context at 15 Stone 7 Pounds
At 15 stone 7 pounds (98.4 kg), your BMI depends entirely on your height. For example, at an average UK male height of 5ft 9in (175cm), a weight of 98.4 kg gives a BMI of approximately 32, which falls into the obese category (Class I) according to NHS guidelines. At 5ft 6in (168cm), the BMI would be around 32.8. At 6ft (183cm), it would be approximately 29.6 — just within the overweight range. Use our BMI calculator above to find your personal BMI and understand what this weight means for your specific height. Even modest weight loss of 5–10% can bring significant health benefits.
