Child BMI calculator is only valid for children between 2 and 20 years.
Body Mass Index, referred to as BMI, is a simple calculation that will estimate body fat based on a persons height and weight. Using this answer you should be able to find your healthy weight range and determine if your over or under weight. BMI is calculated by taking a person’s weight in kilograms and dividing the number by the persons height in meters squared.
BMI calculation in non-metric:
(weight in lbs. / height in inches squared) x 703 = BMI
What’s a healthy BMI? – The BMI Chart
The BMI Chart will help you determine a healthy body mass index based on your BMI score. For adults anywhere from 19 – 25 is considered by many professionals to be healthy. 25 – 30 is considered over weight and over 30 is considered obesity. Going above 40 is considered extremely obese.
Some health professionals say BMI has it’s flaws
While by most standards calculating BMI can be a useful tool. Most won’t take into account for your age and even gender. Someone who has a large amount of muscle mass from healthy exercise, may have a high BMI and be considered overweight. Even though they have a low percentage of body fat. In this case BMI results may not be accurate in determining healthy body mass. The BMI calculator above does use your age and gender.
