Understanding Body Mass Index (BMI)
Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is a convenient rule of thumb used to broadly categorize a person as underweight, normal weight, overweight, or obese based on tissue mass (muscle, fat, and bone) and height.
BMI Categories
This calculator uses the standard World Health Organization (WHO) recommended body weight based on BMI values for adults.
| BMI | Weight Status |

| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 & Above | Obesity |
Disclaimer
The BMI is a general guideline and has limitations. It does not distinguish between fat and muscle mass, and it may not be accurate for all populations, such as bodybuilders, elderly individuals, or pregnant women.
