So, how to calculate BMI knowling the formula above? It is a straightforward task, especially if you already know your height and weight in meters and kg.

Weight is referred to as 'mass' in medical literature, while height is often called 'stature'. Of course, in our online BMI calculator you can enter either SI units or imperial metrics for height (feet and inches) as well as weight pounds for weight. BMI formulaīMI (kg/m 2) = weight (kg) / height 2 (m) See below for a list of BMI categories (classifications). The bigger your calculated BMI is, the greater the risk for cardiovascular complications like hypertension, type II diabetes, some types of cancer, renal disease, degenerative arthritis, gallstones, all of which have links to excessive weight relative to one's heigth. The importance and usefulness of the index and hence any Body Mass Index calculator is in its curvilinear relationship to all-cause mortality.

In general, BMI is useful when applied to adults, but may be ill-suited when used for young children or even teenagers where the waist to hip ratio and body fat estimates may be more informative. The modern term 'body mass index' (BMI) was coined in a paper published in the July 1972 edition of the Journal of Chronic Diseases by Ancel Keys et al., in which it was argued that what was defined as BMI was '.if not fully satisfactory, at least as good as any other relative weight index as an indicator of relative obesity'. The concept of the BMI is due to one Adolphe Quetelet - a Belgian astronomer, mathematician, statistician and sociologist and his work on 'social physics' between 1830 to 1850. Our BMI calculator also requires just these two measurements as input and the output is in the units BMI is measured: kg per square meter (kg/m 2), which is often left out in both writing and speech. The simplicity of the body mass index calculation is one of its advantages: to calculate it one only needs to know his or her weight and height. Body Mass Index (BMI) is an index that attempt to quantify the amount of muscle, fat, and bone mass in an individual, and categorize them as underweight, normal weight, overweight, or obese, based on the index value.
