What is BMI Calculator ?

Body mass index (BMI) Calculator is free app that allows to monitor your BMI and percentage of fat in your body. (BMI) is a measure of body fat based on height and weight that applies to adult men and women. Enter your weight and height using standard or metric measures. Select "Calculate BMI" and your BMI will appear below.

Info:

The BMI may also be determined using a table or chart which displays BMI as a function of mass and height using contour lines or colors for different BMI categories, and may use two different units of measurement.

The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person asunderweight, normal weight, overweight, or obese based on that value. However, there is some debate about where on the BMI scale the dividing lines between categories should be placed. Commonly accepted BMI ranges are underweight: under 18.5, normal weight: 18.5 to 25, overweight: 25 to 30, obese: over 30.

There are criticisms of using the BMI to define obesity in individuals. One is that the BMI was designed for population studies, not individuals. Another is that body fat percentage (BFP) is a more reliable indicator of obesity than BMI: very muscular, lean (low body fat) individuals can be classified as obese using BMI, but are classified as having a normal weight using BFP. An even simpler alternative to the BMI is to define obese individuals as those with a ratio of waist circumference to height of greater than 50%, indicating excess intra-abdomimal fat.

The BMI is generally used as a means of correlation between groups related by general mass and can serve as a vague means of estimating adiposity. The duality of the BMI is that, while it is easy to use as a general calculation, it is limited as to how accurate and pertinent the data obtained from it can be. Generally, the index is suitable for recognizing trends within sedentary or overweight individuals because there is a smaller margin of error. The BMI has been used by the WHO as the standard for recording obesity statistics since the early 1980s.

This general correlation is particularly useful for consensus data regarding obesity or various other conditions because it can be used to build a semi-accurate representation from which a solution can be stipulated, or the RDA for a group can be calculated. Similarly, this is becoming more and more pertinent to the growth of children, due to the fact that the majority of children are sedentary.
