How BMI Calculator Works
The BMI Calculator (Body Mass Index) is an international screening tool used by healthcare organizations to assess whether an individual has a healthy weight in relation to their height. It applies to adult men and women across metric and imperial systems.
Calculation Formula
BMI = Weight (kg) / [Height (m)]²
WHO Asian BMI Cut-off Guidelines
Because Asian populations often have higher body fat percentages at lower BMI levels, healthcare professionals in Southeast Asia recommend the following classifications:
- Underweight: BMI less than 18.5
- Normal Weight: BMI 18.5 – 22.9
- Overweight: BMI 23.0 – 24.9
- Obese: BMI 25.0 and above
Disclaimer: BMI is a screening metric and does not distinguish between muscle mass and fat tissue. Consult a physician for clinical health assessments.
Frequently Asked Questions
