Body mass index is a number used to compare a person's height to their weight. It's often
a rough measure to dertermine if somebody is underweight, a healthy weight, or obese.
An adult BMI between 18.5 and 25 is generally considered healthy. BMI is calculated the same
way for both men and women.
Compare body mass index by height (feet and inches) and weight (lbs)
