About BMI Calculator

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 meters squared. BMI indicates whether a person has a healthy body weight for their height.

BMI Categories
  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 to 24.9
  • Overweight: BMI 25 to 29.9
  • Obesity: BMI 30 or greater
Important Notes

While BMI is a useful screening tool, it does not directly measure body fat or account for muscle mass, bone density, overall body composition, and racial and sex differences. For a comprehensive health assessment, consult with a healthcare provider.
