This tool allows you to calculate your body Mass Index (BMI) instantly. All you need is your height (in centimetres) and weight (in kilograms). Remember to click on the BMI box to get your results. Alternatively, you can use the tool employing Imperial (English) measurements. For that tool, found on the next page, you will need to enter your height in feet and inches and your weight in pounds (not stones).

Go ahead, check where you are. It is free.
