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.

To convert 71.4kg to stone, divide the kilogram value by 6.35029. The exact conversion result is 11 stone 3.2 pounds. Here's the conversion formula: weight in stone = kilograms ÷ 6.35029.

71.4kg BMI and Healthy Weight Context
At 71.4kg, your BMI depends on your height. For example, at an average UK height of 1.68m (5ft 6in), a weight of 71.4kg gives a BMI of 25.3 — just above the healthy weight range of 18.5–24.9. At 1.73m (5ft 8in), the same weight gives a BMI of 23.9, which falls squarely within the healthy range. Use our free BMI calculator above to check your personal BMI instantly based on your exact height and weight. Remember that BMI is a screening tool — it doesn't account for muscle mass or where fat is stored, so speak to your GP if you have questions about what your BMI means for your individual health.
