BMI Calculator

What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.

BMI is used to categorize weight status and potential health risks. While it's not a perfect measure (it doesn't account for muscle mass, bone density, or fat distribution), it's a useful screening tool for adults.

Limitations of BMI

While BMI is a useful screening tool, it has limitations:

• Doesn't distinguish between muscle and fat
• May overestimate body fat in athletes
• May underestimate body fat in older adults
• Doesn't account for fat distribution (belly fat vs. other areas)
• Different cutoffs may apply for certain ethnic groups

Note: Always consult with a healthcare provider for a complete health assessment.
