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 Inches to Centimetres
The conversion formula is simple: multiply inches by 2.54 to get centimetres. So 6.8 inches × 2.54 = 17.27 cm exactly.
- 6.8 inches = 17.27 cm
- This measurement is useful for body measurements, height tracking, and fitness assessments
- UK health services often use centimetres, so conversion helps with NHS health information and medical records
- For height conversions, 6.8 inches represents approximately a quarter of an inch under 5 feet 7 inches
Use our free weight converter above to switch between imperial and metric measurements for your health data. Understanding UK health guide measurements in both systems helps you track progress and communicate with healthcare providers effectively.

Common Height and Measurement Conversions

- Small measurements like 6.8 inches commonly appear in body composition assessment
- BMI calculator tools on this page accept both inches and centimetres for flexibility
- Medical records, NHS guidance, and weight management programmes increasingly use metric measurements
