## What is BMI?

BMI is an abbreviation for Body Mass Index. We derive BMI from the mass and height of a person to determine whether a person is underweight, normal weight, overweight, or obese . It’s a person’s body mass divided by the square of the body height.

BMI is measured in kg/m2 as the universal unit of measurement. For instance, a BMI of 18 means it’s 18Kg/m2. BMI has come to be widely used for preliminary diagnoses in the the world of medicine and fitness due to its simplicity,.

## How To Calculate BMI

All you need to know is your mass(weight) in Kilograms and your height in Meters. Then you can use this formula:

### Example:

Suppose a person weighs **68 Kg** and has a height of **1.5** Meters find that person’s BMI.

The BMI of that person is 30.2 Kg/M2.

Then we use this value to determine, from a chart, whether your weight is OK, too much, too little e.t.c.

This clearly shows that our guy in the example who had a BMI of 30.2kg/M2 is moderately obese. (Obese Class I)
