About BMI
What is BMI?
Body Mass Index (BMI) is a simple calculation using your height and weight. The formula is BMI = kg/m² where kg is your weight in kilograms and m² is your height in metres squared.
How is it calculated?
BMI is calculated by dividing your weight (in kilograms) by your height (in metres) squared. For example: BMI = 70 kg ÷ (1.75 m × 1.75 m) = 22.9
Important Notes
- BMI is a screening tool, not a diagnostic tool
- It doesn't measure body fat directly
- Results may not be accurate for athletes with high muscle mass
- Consult a healthcare professional for personalised advice
Limitations
BMI doesn't distinguish between muscle and fat mass, age, sex, or bone density. It's best used as a general screening tool alongside other health assessments.
