About BMI: Body Mass Index (BMI) is a simple screening ratio that divides a person's weight by their height squared. While a good general population tracker, it does not distinguish between muscle tissue mass and body fat mass. Use the US Navy Body Fat Calculator for body composition breakdowns.

Disclaimer: BMI is a screening tool only and does not directly measure body fat. Results may be misleading for athletes, older adults, and children. Consult a healthcare professional for medical advice.
