BMI Calculator

What is BMI?
Body Mass Index (BMI) is a widely used measure to assess whether a person has a healthy body weight relative to their height. It is calculated by dividing weight in kilograms by the square of height in meters (kg/m²).
BMI Categories
- Underweight: BMI below 18.5
- Normal weight: BMI 18.5 – 24.9
- Overweight: BMI 25 – 29.9
- Obese: BMI 30 or above
How to Use This Calculator
Simply select your preferred unit system (metric or imperial), enter your weight and height, and click "Calculate BMI". The calculator will instantly show your BMI value, health category, and a visual indicator on the BMI scale. It also displays your ideal weight range based on your height.
Limitations of BMI
BMI is a useful screening tool but does not directly measure body fat. It may overestimate body fat in athletes and muscular individuals, and underestimate it in older adults who have lost muscle mass. For a comprehensive health assessment, consult a healthcare professional.
