BMI calculation for kids

BMI: An Overview

Body mass index is known as BMI. Basically, it is a degree of anyone’s body size. BMI calculators for kids or adults conglomerates the weight with their height. The final outcomes of a BMI measurement provide an indication about whether any being has a precise and accurate weight for their height. We can say that the body mass index or BMI is a screening tool.

The purpose of this tool is to indicate whether human beings are:

  • Malnourished or if they are hale and hearty with perfect weight.
  • Superfluous weight, or condition of obesity.

If any one’s BMI is beyond the normal healthy range, their fitness or health menaces may proliferate meaningfully. BMI does not provide any indication about the body fats. Age, sex, ethnicity, or muscle mass in human beings have nothing to do with BMI in the case of adults. If doctors or health caretakers want to identify risks and potential issues related to health in human beings, then BMI will be a perfect tool as it uses only standard weight status categories.

BMI Calculation In Adults


  • In order to calculate the BMI in metric units, you can use the BMI formula that is: BMI = kg/m2.
  • For the calculation of an adult’s BMI, you can simply divide the weight of the individual in kilograms (kg) by the square of height in meters (m2).


  • If someone is using imperial units, then the formula is different: BMI = lbs. x 703/in2
  • In most simple words: you have to multiply the weight of the individual in pounds (lbs.) by 703. In the next step, you have to divide by their height in inches, squared (in2). For more convenience and to avoid mathematical reasoning, one can simply use a calculator or a chart online to indicate their BMI.
