What Is Body Mass Index (BMI)?
Body Mass Index (BMI) is an internationally recognized screening metric defined by the World Health Organization (WHO) to categorize body mass relative to height. Calculated as weight in kilograms divided by height in meters squared ($BMI = kg / m^2$), it provides a baseline indication of whether an individual falls within an underweight, healthy, overweight, or obese classification.

| Underweight | < 18.5 | Nutritional deficiency risk |
| Normal Weight | 18.5 – 24.9 | Optimal health & lowest statistical disease risk |
| Overweight | 25.0 – 29.9 | Elevated cardiovascular consideration |
| Obese (Class I-III) | ≥ 30.0 | High clinical risk factor |
Frequently Asked Questions
Is BMI accurate for athletes and bodybuilders? ↓
BMI does not distinguish between muscle mass and adipose tissue (fat). Muscular athletes may register as "overweight" or "obese" despite having very low body fat percentages.
Does this calculator support both pounds and kilograms? ↓
Yes. You can switch seamlessly between Metric (kilograms and centimeters) and Imperial (pounds, feet, and inches) at the top of the workspace.
Is BMI appropriate for children and adolescents? ↓
Standard BMI scales apply to adults aged 20 and over. Pediatric evaluation requires percentile-for-age charts published by the CDC or WHO.
