BMI or Body Mass Index is a measurement of a person’s leanness or corpulence based on their height and weight and is expected to measure tissue mass. It is broadly utilized as a general indicator of whether an individual has a healthy body weight for their height. In particular, the value obtained from the calculation of BMI is used to categorize whether an individual is underweight, ordinary weight, overweight, or obese depending on what range the value falls between. These scopes of BMI differ dependent on components like region and age and are at times additionally divided into subcategories, for example, severely underweight or severely fat.

Being overweight or underweight can have huge wellbeing impacts, so while BMI is an imperfect measure of healthy body weight, it is a useful indicator of whether any additional or testing is required. Checkout the below methods to see the different categories based on BMI that is used by calculator.

Methods To Be Followed While Calculating Body Mass Index (BMI):

Method 1: Using Metric Measurements

Step #1: At first take your height in meters and square the number. First of all, you need to change your height in meters to calculate it accurately. For example, if you are 1.75 meters tall, then you would multiply 1.75 by 1.75 and get a result of approximately 3.06 M2

HIEGHT = 1.75 METERS

SQUARE OF HEIGHT=  (1.75 X 1.75) METER SQUARE

                                 =  3.06 METER SQUARE

Step #2: Divide your weight in kilograms by meters squared After that, divide your weight in kilograms by your squared height in meters. 

For eg, if your weight is 75 kilograms and your height is 3.06 meters squared, you would divide 75 by 3.06 to get a BMI of 24.5.  kg/m2 is the full equation, with kg 

Equaling your weight in kilograms and m equaling your height in meters.

• Weight = 75 kilogram

• Square of height = 3.06 m^2`
• BMI= 75/ 3.06 = 24.5 kg/m^2

Example:

• Weight =  60 kilogram

• Height= 162 centimeter  or 1.62 metre
• Height square = 1.62 x1.62=  2.62 m^2
• BMI = 60 / 2.62 = 22.900  kilogram/ metre^2

Use an extended equation if your height is in centimeter

If your height is in centimeters, you can still measure your BMI, but you’ll need to use a slightly different equation. Your weight in kilograms divided by your height in centimeters, then divided by your

 height in centimeters, then multiplied by 10,000 in the equation. 

• For instance, if your weight in kilograms is 60 and your height in centimeters is 152, you will divide 60 by 152 to get 0.002596 (60 / 152 / 152). When you multiply this number by 10,000, you get 25.96, or approximately 26. This person’s BMI is estimated to be around 26.
• You can also convert the height from centimeters to meters by shifting the decimal two places to the left. Then, by squaring your height in meters and dividing your weight by your height in meters squared, you can calculate your BMI. 1.52 multiplied by 1.52 equals 2.31, for example. If you weigh 80 kilograms, divide the number by 2.31 to get a BMI of 34.6.

Method 2: Using imperial measurements

Step 1:

 Square your height in inches 

To square your height, multiply it by itself in inches. If you’re 70 inches tall, for

 example, multiply 70 by 70. In this case, your answer will be 4,900.

Step #2:

Divide your weight by height

•  Weight = 180 pounds
• Height square = 4900 inch^2
•  Weight/ height^2 = 180 / 4900 = 0.03673

• Body mass index(BMI) = 0.03673 x 703 = 25.8

Step #3:  

Multiply that answer with 703

• BMI Calculation will help you to understand whether you are at a healthy weight
  

Your BMI is important because it will help you decide whether you are overweight, normal weight, or obese.

If your BMI indicates under 18.5 it shows that you are underweight.

A balanced BMI range is 18.6 to 24.9.

You are overweight if your BMI is between 25 and 29.9.

Obesity is described as a BMI of 30 or higher.

• Use your BMI to see if you are a candidate for bariatric surgery.

If you want to have bariatric surgery, your BMI may need to be over a certain amount in some cases. To be eligible for bariatric surgery in the United Kingdom, for example, you must have a BMI of at least 35 if you do not have diabetes and a BMI of at least 30 if you do.

• Track changes in your BMI over time. 

You can also use your BMI to keep track of your weight changes over time. Calculating your BMI regularly, for example, can be useful if you want to monitor your weight loss. If you want to keep track of your or your child’s progress, measuring and monitoring BMI is another option.

• With Above Methods Calculate Your BMI Before Taking Any Expensive Options

Healthy body weight is described as one with a BMI of less than 25. Your BMI, on the other hand, could be higher if you have a higher-than-average muscle percentage. In that case, having a BMI greater than 25 does not necessarily mean you are obese. If you have a lot of muscle, you can have skin fold tests to see if you have too much fat.

Underwater measuring, dual-energy x-ray absorptiometry (DXA), and bioelectrical impedance are some of the other options for assessing the body’s fat content, in addition to skin fold tests. Remember that these approaches are more costly and invasive than measuring Body mass index.
