BMI Calculator (Metric)

What is Body Mass Index (BMI)?

Body Mass Index (BMI) is a medical indicator that helps assess whether a person's weight is appropriate for their height. The BMI calculator uses the formula: BMI = weight (kg) ÷ height² (m). This indicator is widely used by healthcare professionals to categorize weight status.

BMI Categories and Their Meaning

• Underweight: BMI less than 18.5
• Normal weight: BMI 18.5-24.9
• Overweight: BMI 25.0-29.9
• Obesity: BMI 30.0 and above

How to Calculate BMI Manually?

To calculate body mass index step by step:

1. Measure your weight in kilograms
2. Measure your height in centimeters and convert to meters
3. Square the height value
4. Divide weight by the obtained value

Example: With 70 kg weight and 175 cm height: BMI = 70 ÷ (1.75)² = 22.86
