BMI =

Body Mass Index (BMI) is a person's weight in kilograms divided by their height in meters, squared (kg/m2). Drag the sliders or type in the boxes to enter your height and weight in the units of your choice. Your BMI is automatically shown above.

BMI is not an exact indicator of healthy and unhealthy weight, but it is a useful guideline.

BMI does not show the difference between excess fat and muscle, but BMI is closely associated with body fat percentage. There is also a correlation to the development of health problems related to excess weight, and BMI is widely used by health care providers.

A sensible exercise and diet program can reduce body fat and therefore BMI.

Note: You can convert higher and lower amounts than are available using the sliders by typing directly in the boxes.
