How to Calculate Body Mass Index
Are you looking your body on mirror then you feel something was happened? or you scaled your weight then you feel that your body was changed? Or you say: “I am not thin like before. I am fatty now”. Do you feel that you are obese?
Okay don’t define that you are fatty or obese before you calculate it by Body Mass Index (BMI). Here is a way how to calculate your Body Mass Index.
What is Body Mass Index?
Body Mass Index (BMI) is a statistical measure of the weight of a person scaled according to height (wikipedia.com)
The BMI is used to access how much an individual’s body weight departs from what is normal or desirable for a person of his or her height.
How to Calculate BMI?
BMI is defined as the individual's body weight divided by the square of the height. It almost always expressed int the unit kg/m2.
Categories of BMI
The common definition of BMI categories are followed here:

Categories of BMI
The common definition of BMI categories are followed here:
- Starvation: less than 15
- Underweight: lest than 18.5
- Ideal: from 18.5 to 25
- Overweight: from 25 to 40
- Obese: from 30 to 40
- Morbidly Obese: greater than 40
Typically a BMI of less than 18.5 is considered underweight and may indicate malnutrition (eating disorder) or other health problem. A BMI greater than 25 is considered overweight and above 30 is consider obese.
These Body Mass Index values I mentioned above are valid only for adult. However Body Mass Index for children can be calculated as same way as adult, but then compared to typical values for other children of the same gender and age. A BMI that is less than the 5th percentile is considered underweight and above the 95th percentile is overweight. Children with a BMI between the 85th percentile and 95th percentile are considered to be at risk of becoming overweight.
There is a recommendation of lowering the normal BMI for South East Asian to around BMI 23 and expects further revisions to emerge from clinical studies of different body types. For Asians, the new cut-off BMI index for obesity is 27.5 compared with the traditional WHO figure of 30. An Asian adult with a BMI of 23 or greater is now considered overweight and the ideal normal range is 18.5-22.9. For South East Asian people I recommend you to see Singapore BMI cut-offs or you click here.
There are so many websites providing online instrument for calculating your BMI. You just fill the form of your weight and height and let them to calculate it for you.
