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 71.5 Inches To Centimetres
The conversion from inches to centimetres uses a simple, exact formula: 1 inch = 2.54 cm exactly. To convert 71.5 inches to centimetres, multiply 71.5 by 2.54.
71.5 inches × 2.54 = 181.61 cm
This height measurement is useful for many UK health contexts. The NHS uses centimetres for clinical measurements, so converting your height to cm helps when discussing health matters with your GP or using NHS health guidance resources. If you're tracking weight management or fitness progress, having your height in both imperial and metric makes it easier to calculate BMI and understand healthy weight ranges for your frame.
