Calculation of Body Mass Index:

Your BMI is an objective scientific measure that uses your height and weight. You can calculate your BMI by dividing your weight in kilograms by the square of your height in meters. In other words the algebraic expression for BMI is:

BMI = Kg / (m)²

One variable BMI fails to consider is lean body mass. It is possible for a healthy, muscular individual with very low body fat to be classified obese using the BMI formula. If you are a trained athlete, your weight based on your measured percent body fat would be a better indicator of what you should weigh. To use the program enter your height in meters and weight in kilograms, in the boxes below, and then click “Calculate.” For those unfamiliar with the “MKS” system, listed below are relevant unit conversion factors, and an example of English to metric unit conversion.

1 inch = 2.54 cm

1 meter = 100 cm

1 lb = 0.45359237 Kg

For example:

5 feet 8 inches = 5 ft (12 in / ft) + 8 in = 68 inches

68 in (2.54 cm / in) = 172.72 cm

172.72 cm (1 meter / 100 cm) = 1.7272 meters

and

139 lbs (0.45359237 Kg / 1 lb) = 63.0493853 Kg
