About BMI
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in metres squared.
A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18–65 years.
BMI is not always accurate for everyone. It may not be suitable for athletes, pregnant women, children, or elderly people. Always consult with a healthcare professional for a complete health assessment.
