BMI Calculator – Calculate Body Mass Index Accurately
A BMI Calculator is a health assessment tool used to calculate Body Mass Index (BMI) based on a person’s height and weight. BMI is widely used to screen for potential weight-related health risks and to categorize individuals into weight ranges.
This online BMI Calculator provides an instant BMI value along with the corresponding weight category based on World Health Organization (WHO) standards.
What Is Body Mass Index (BMI)?

BMI is calculated using the formula:
BMI = Weight (kg) ÷ Height² (m²)
BMI Categories (WHO Standard)
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obese: BMI 30 and above
