Body Mass Index (BMI) is a statistical measure of a person's weight scaled according to height.

BMI is frequently used to find out how much an individual's body weight departs from the normal or desirable weight for a person of his or her height.

BMI makes simple assumptions about the distribution of muscle and bone mass, and thus may be misleading. It overestimates "fatness" of athletic people, while underestimating obesity of the elderly.

To calculate your BMI:

1. Select your gender
2. Select Metric (kg/m/cm) or Imperial (lb/ft/in) units
3. Enter your height and weight
4. Tap the Calculate button

As soon as you tap the Calculate button, your input and the calculated result are stored in the History table. Next time when you open the BMI page, you will see your last input as the default numbers. This way you only have to change the numbers that changed since the last time when you used this calculator.

Tap on the History button to see the history table.
