⚖️ BMI Calculator - Complete Guide

What is BMI (Body Mass Index)?

Body Mass Index (BMI) is a numerical value derived from your weight and height. It's a widely used screening tool to categorize individuals into weight status categories that may indicate health risks.

BMI Formula:

BMI = weight (kg) / [height (m)]²

Or in imperial units: BMI = [weight (lb) / height (in)²] × 703

BMI provides a simple, quick assessment of body fat and potential health risks associated with being underweight, normal weight, overweight, or obese.

Understanding Your Results

What Your BMI Means

Your BMI is a screening tool, not a diagnostic tool. It indicates whether your weight falls within a healthy range for your height.

Examples

Limitations of BMI

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

• ⚠️ Muscle Mass: Athletes and bodybuilders may have high BMI due to muscle, not fat
• ⚠️ Age: BMI doesn't account for age-related muscle loss in elderly
• ⚠️ Gender: Women typically have more body fat than men at the same BMI
• ⚠️ Ethnicity: Health risks vary by ethnic group at the same BMI
• ⚠️ Body Composition: Doesn't distinguish between fat and muscle mass
• ⚠️ Fat Distribution: Doesn't indicate where fat is located (visceral vs. subcutaneous)

Note: BMI should be used alongside other assessments like waist circumference, body fat percentage, and overall health evaluation.
