How To Calculate BMI

BMI is a simple tool to decide whether you are healthy according to your height and weight. It is used by many people to determine their healthiness. Basically, it has a range which defines a person is overweight or underweight or normal. If a person is underweight, he/she is lacking the essential vitamins and minerals required for the normal body function such as immune system function. If a person is overweight, he/she can meet several health issues such as heart problems, joint pain, diabetes, etc. 

Body mass index is calculated by dividing the weight of a person by the square of the height of that person. If the unit of the weight will be Kg and the unit of the height will be meter, then the unit of BMI will be Kg/m^2. 

What is the Formula to Find BMI?

Formula to Find BMI

BMI is also known as the Quetelet index. It is a value determined by taking a person’s weight and height and calculating with the BMI calculator. This calculator can let the person know his/her health condition, i.e. overweight or obese, underweight or normal. The formula for calculating the BMI is 

BMI = weight/ height^2 

If we take the unit of the weight as Kg and the unit of the height as meter, then the unit of the BMI will be Kg/m^2. This formula is called a metric formula. 

There is also another formula to calculate the BMI, which is known as an imperial formula. 

The imperial formula for calculating the BMI is 

BMI = Weight x 703/ height^2

In the imperial formula, the unit of the weight is a pound and the unit of the height is inch.

Body mass index or BMI tells your health condition from your height and weight. In fact, this tool is widely used to determine a healthy weight. However, by considering the BMI result one shouldn’t determine his/her health condition. As per the BMI calculation, a person is underweight if the BMI result is below 18.5, a person is overweight if the BMI result is between 25 and 29.9 and obese if the BMI result is above 30. A person is considered as normal weight or healthy weight if the BMI result lies in between 18.5 and 24.9.

According to the experts, the BMI result is inaccurate because the result is predefined and a person’s health condition can’t be defined by just weight and height. Also, BMI doesn’t consider the muscle mass, overall body composition and the sex difference, etc. while calculating the health condition. As the muscle mass and other health conditions are not taken into account to calculate the overall health condition in the BMI calculation process it is not considered as an effective method to determine the health condition.

What is the BMI Chart?

BMI or body mass index tells a person’s weight is healthy or not. It takes your height and weight to calculate your healthy weight. The BMI result tells a person about his/her health problems. 

BMI chart is used to define the BMI of a person. To use the BMI chart you need to take the height and weight of a person and find out the BMI using the BMI formula. Then use the BMI chart to know your BMI. The BMI chart is categorized into two types according to the weight. One chart is used by the people under 200 pounds and another chart is used by the people above 200 pounds. So you can use the BMI chart according to your category. From the BMI chart, you can find out below results. 

  • Underweight: – the BMI result is less than 18.5. 
  • Normal weight: – the BMI result is between 18.5 and 24.9.
  • Overweight: – the BMI result is between 25 and 29.9. 
  • Obese: – the BMI result is 30 or above. 
  • Again the obesity is classified into further three categories. 
  • Class 1 obesity: – BMI is between 30 and 34.9.
  • Class 2 obesity: – BMI is between 35 and 39.9. 
  • Class 3 obesity: – the BMI is above 40. 

The BMI chart is a guide for healthy weight. It can’t define that a person has an ideal weight or not. For example, if a bodybuilder has a high BMI due to his/her muscles, it can’t be said that he/she is overweight.
