You can always keep an eye on your weight by regularly using a weighing machine. But how exactly would you know whether your weight is within normal limits? How would you know if you're overweight or obese? Well, Body Mass Index (BMI) is one of the globally accepted standard of defining obesity. Today, we will know more about BMI.
Body Mass Index or BMI is a measure that is calculated from a person's height and weight. Definition of BMI is:The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m2, resulting from mass in kilograms and height in metres.
BMI value is used to categorize a person as underweight, normal weight, overweight or obese.
WeCapable has developed a free online BMI calculator that takes your weight (in kilograms or in pounds) and height (in centimeters or inches) as input and calculates BMI value for you. It also interprets the BMI value as per the WHO standards to informs you if you are underweight, normal weight, overweight or obese.
If you're using the metric measurement system, formula for BMI calculation would be:
BMI = Weight in Kilograms / (Height in Meters) x (Height in Meters)
And if you're using the Imperial system of measurement, formula for BMI calculation would be:
BMI = ( Weight in Pounds / (Height in inches) x (Height in inches) ) x 703
BMI value is universally calculated and expressed in metric measurement (kg/m^2). When pounds and inches are used, the value is multiplied by the conversion factor of 703.
The following table gives the classification of BMI value as decided by the WHO:
|Very severely underweight||15|
|Normal (healthy weight)||18.5||25|
|Obese Class I (Moderately obese)||30||35|
|Obese Class II (Severely obese)||35||40|
|Obese Class III (Very severely obese)||40||45|
|Obese Class IV (Morbidly Obese)||45||50|
|Obese Class V (Super Obese)||50||60|
|Obese Class VI (Hyper Obese)||60|
BMI value is nowadays considered a benchmark for deciding if a person is overweight. It is very important to know status of one's weight because a lot of other medical conditions have a relation with obesity.
