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.
How to Convert Stone and Pounds to Kilograms
Converting 10 stone 6 pounds to kilograms uses a straightforward formula. One stone equals 6.35029 kg, and one pound equals 0.453592 kg. To calculate: (10 × 6.35029) + (6 × 0.453592) = 63.5029 + 2.7216 = 66.22 kg (rounded to 66.68 kg for practical purposes).
The weight converter on this page performs this calculation instantly — simply enter your weight in stone and pounds, and it displays the kg equivalent automatically. This eliminates a UK pharmacy calculation errors and is useful when consulting NHS guidance, booking health appointments, or tracking weight management progress.
For context, 66.68 kg falls within the overweight category for most UK adults, depending on height. Your GP can assess what this means for your individual health using the NHS BMI guidelines.
