BMI - Body Mass Calculator

Body Mass Index or BMI correlates with body fat. The relation between fatness and BMI differs with age and gender. For example, women are more likely to have a higher percent of body fat than men for the same BMI. On average, older people have more body fat than younger adults with the same BMI.

Remember that BMI is a formula that uses weight and height to estimate body fat and gauge health risks due to carrying too much weight. The BMI is only one factor in determining a person's health risk. A BMI in the "healthy" range does not necessarily mean that you are fit and healthy!

BMI does not take into account lean body mass or body frame. A muscular, large-framed person's BMI could indicate obesity, but other indicators would show that this is not the case.

Two people can have the same BMI, but a different percent body fat. A bodybuilder with a large muscle mass and a low percent body fat may have the same BMI as a person who has more body fat because BMI is calculated using weight and height only.
