What Is BMI?

BMI is actually used for measuring corpulence or leanness of the person depending on their weight and height. It is used for the quantification of tissue mass. Even though there are limitations to BMI in the fact that it can’t consider body composition, you can consider it general indicator for healthy body weight depending on the height of the person. The BMI value is used widely for categorizing people into different categories like underweight, overweight, normal weight, or obese according to the range in which their BMI value falls. The BMI ranges can vary according to different factors like age and region and at times there is sub-categorization like severely obese or severely underweight. However, because of so many different types of bodies out there and distribution of bone mass, muscle, and fat, one should consider BMI in relation to various other measurements to get the most accurate results.

BMI Formula

Here is how BMI is calculated in SI and US system using a person with 5'10" height and 160-pound weight for the example:

 USC Units: BMI = 703* mass (lbs) / height2 (in) = 703* 160 / 702 = 22.96 kg / m2 SI, Metric Units: BMI = mass (lbs) / height2 (in) = 72.57 / 1.782 = 22.90 kg / m2
