What is BMI (Body Mass Index)?

A useful measurement that evaluates a person’s weight in relation to their height is the body mass index (BMI). BMI calculates a person’s perspective of body fatness by multiplying their weight in kilograms (or pounds) by the square of their height in meters (or feet). It works as a screening tool to find weight ranges that can cause health problems. It’s crucial to remember that BMI does not, by itself, provide a diagnosis of an individual’s body fatness or general health.

As a starting point for assessing, one’s weight status, it should be interpreted with a human touch, considering other elements including muscle mass, bone density, and individual variances in body composition. It’s critical to speak with medical experts for a thorough evaluation and individualized treatment.

History of BMI.

The formula for BMI was devised in the 1830s by Belgian mathematician Adolphe Quetelet and it is expressed in kg/m2.

The modern term “body mass index” (BMI) for the ratio of human body weight to squared height was invented in a paper published in the July 1972 edition of the Journal of Chronic Diseases by Ancel Keys and others.

Calculation for BMI?

BMI = weight (in kg) / [height (in meter)]2

Simple steps for calculating BMI is as follows:

1. Measure your heights in Meter of centimeter

2. Square of your height.

3. Weight in Kg divided by square of your height.

Scale and category of BMI:

BMI calculator Scale

healthy weight range is 18.5 to 25.


Let’s your height is 170 centimeters and weight is 80 kg, in first step convert it into meter i.e 170 cm= 170/100 meter= 1.7 meter and square of height = (1.7)2 =1.7×1.7= 2.89 m2

then in second step weight is divided by square of height= 80/2.89= 27.68.

Means your BMI is 27.68 and you are in “Overweight” zone.

Limitations of using BMI:

BMI Doesn’t measure distribution of fat in your body as well as doesn’t consider family history for disease i.e. diabetes, high cholesterol, high blood pressure and cancer. Other than that muscle mass, health problems, measure of body fat, etc. not measure.
