BMI Calculator

The Body Mass Index (BMI) Calculator helps assess whether your weight is in a healthy range for your height. BMI is a widely used screening tool for weight-related health risks.

How BMI is Calculated:

BMI = weight (kg) / height (m)²

For imperial units: BMI = (weight in pounds × 703) / (height in inches)²

BMI Categories:

• Underweight: BMI less than 18.5
• Normal weight: BMI 18.5-24.9
• Overweight: BMI 25-29.9
• Obese: BMI 30 or greater

Important Notes:

• BMI is a screening tool, not a diagnostic measure
• It doesn't account for muscle mass, bone density, or body composition
• Athletes may have high BMI due to muscle mass
• Consult healthcare providers for personalized health assessment
• BMI may not be accurate for pregnant women, elderly, or children

Limitations:

• Doesn't distinguish between muscle and fat
• May not reflect health risks for all populations
• Age and gender differences not considered
• Doesn't measure body fat distribution
