What is BMI?

Body Mass Index (BMI) is an international measure used to determine whether a person is at a healthy weight. It is calculated by dividing weight in kilograms by the square of height in meters.

BMI Formula

BMI = weight (kg) ÷ height² (m²)

Example: Weight = 70kg, Height = 1.75m

BMI = 70 ÷ (1.75 × 1.75) = 70 ÷ 3.0625 = 22.86

BMI Limitations

BMI doesn't distinguish between muscle mass and body fat. Athletes with high muscle mass may have a high BMI while being perfectly healthy. Always consult a healthcare professional for a complete assessment.
