Learn how to calculate BMI, all you need is knowledge and a calculator

A Bmi Calculator For Teenagers is not the easy, foolproof clinical tool. This is because the name of the BMI, or basic metabolic index, can be misleading, especially when applied to children and teenagers.  Children and teenagers are involved in one of the costliest energy expenditures there is—growth.  This growth is something simply not seen in adults, who are by definition mature, and no longer growing, or adding inches to their height or capabilities to the repertoire.  A good example of this growth is the difference between a newborn baby and a year-old child.  The baby has a hard time seeing, and is not capable of things like rolling over or sitting upright while unsupported.  The year-old child, on the other hand, can do both as a result of the growth experienced in a years' worth of growth.  On the other hand, the infant is growing at a rate unequaled at any other time of life.  The typical 6lb to 7lb newborn will, at the end of a year's growth, weight somewhere in the neighborhood of 20lbs to 30lbs, and what is obviously not a healthy weight for a newborn becomes a very healthy weight for a year-old child.

The same thing, to a somewhat smaller degree, happens during puberty and throughout the teenage years.  A typical teenager will add 1-6 inches to their height during this time, depending on gender and heredity.  Therefore, what is obese at one stage of life can become a healthy weight a few months or years later.  For instance, a child who is 4'9” and 125lbs at age 10 has a BMI of 27.0, placing this BMI in the 98^th percentile and is classified as obese, while a child who is 5'4” a few years later has a BMI of 21.5, placing her in the 70^th percentile and giving her a healthy weight.  Such gains in height are not uncommon during the teen years, especially for boys, but even girls can gain 4”-6” in less than two years.

Therefore, the Bmi Calculator For Teenagers contains the height and weight like the BMI for adults, but is also weighted for age.  Therefore, instead of the simple weight or height multiplied by 703 that it is for adults, for children and teenagers the results are plugged into a chart distributed by the CDC, which evaluates the results against the child's gender and age in addition to the basic formula used by adults.
