## Body Mass Index Calculation in Kilograms

BMI stands for Body Mass Index, it is a tool to measure the fat content in the human body. Based on the BMI value, we can easily identify whether the person is normal, under weight, over weight or obese for their height. Here is the simple tutorial to find the BMI Level when provided weight in kilogram(kg). BMI Chart :
You can refer to the below chart to find your BMI level is under which category.

 BMI Range(kg/m2) Category <16 Severe Thinness 16 - 17 Moderate Thinness 17 - 18.5 Mild Thinness 18.5 - 25 Normal 25 - 30 Overweight 30 - 35 Obese Class I 35 - 40 Obese Class II > 40 Obese Class III

Metric Body Mass Index (BMI) Formula :
Here provided the BMI formula in Metric units.
BMI in Kg = Weight (kg) / [height (m)]2
or
Body Mass Index in Kilograms = [weight (kg) / height (cm) / height (cm)] x 10,000 You can click on the link to find the BMI value in Imperial units using weight in pounds and height in inches. BMI Calculation using SI Units
Steps to Follow
Step 1: Lets us consider that a weight of a boy is 65kg and height is 175cms. Calculate the BMI range?
Weight - 65 kg
Height - 175 cms Step 2: Convert height in centimetres to metre.
In common height is measured in cms. To convert the cm into meter, just divide the weight in cms by 100 to convert into metres.
1 centimetre = 0.01 metre
175 centimetre = 175 / 100 metre
175 centimetre = 1.75 metre Step 3: Substitute the values in the BMI formula.
BMI in Kg = Weight (kg) / [height (m)]2
= 65 / (1.75 x 1.75)
= 65 / 3.0625
= 21.22 kilograms/meter2 When referred with the above BMI Chart, the Body Mass Index Level of the boy is Normal.
