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.

BMI is a useful measure of overweight and obesity. It is calculated the same way for both adults and children. However, it is interpreted differently for children than it is for adults.

⚠️ Important Notes

  • BMI is a screening tool and is not intended to diagnose disease or illness.
  • BMI does not measure body fat directly and may not be accurate for athletes or people with high muscle mass.
  • For children and teens (ages 2-19), BMI is calculated differently and uses age and sex-specific percentiles.
  • Always consult with a healthcare provider for proper medical advice and diagnosis.
  • BMI may not be accurate for pregnant women, elderly individuals, or people with certain medical conditions.
