How is Body Mass Index (BMI Calculated)?

The Body Mass Index (BMI) is also called as the Quetelet Index because it was devised by the astronomer named Adolphe quetelet. The new term Body Mass Index was only coined later when it was published in a paper in July 1972.

It is a value that indicates the amount of the body tissues present in the any individual. It is usually calculated to see where the individual stands in terms of body dimension among the masses. Based on the value obtained by the Body Mass Index (BMI Calculator) of each individual they are classified into

  • Underweight
  • Overweight
  • Normal weight

However, there is still controversy on where the margins should be placed to diversify the individual into these categories.  The BMI is globally expressed in Kg/m2 because of kilograms in mass and height in meters. BMI is directly proportional to the mass and indirectly proportional to square off the height. So if the dimension of the body doubles the BMI also doubles.

Formula for BMI Calculation

The BMI is usually calculated by the formula

BMI = mass Kg/ height2 m

It is actually helpful in viewing the person’s thickness or thinness in an objective manner with a numerical number for the doctors and physicians, so that they can come up with the effective diet plan.

Commonly accepted BMI value range for the these three categories are

  • Below 18.5 Kg/m2 for underweight
  • From 18.5 to 24.9 kg/m2 for normal weight
  • From 25 to 29.9 for overweight
  • Above 30 kg/m2 for obese

People of Asian descent and European descent have different associations with percentage of fat, health risks etc.
