The Broca-Formula, named by Paul Broca, a frech doctor for the military, is very simple and everybody can calculate it without problems. Everybody born before 1975, can remember this formula, because it was used in his childhood.

BMI and science
But there is a problem with the Broca-Formula. When you need to compare a big group of humans, you need one value wich can compared with others. So the BMI is perfect for this. Size and weight togehter in one reference number.n.

American assurance
One urban myth is the origin of BMI at american assurance. They shall have invented the Body Mass Index to calculate health risk. Maybe they have used the BMI, but it's not invented by them.

The simple solution in body fat scales with electric power is quite unaccurate. This is the reason of taking the BMI as simple value.

BMI Formula

The Body Mass Index is calculated by the following formula:

body weight in Kilogramm divided by body height in Meter to the second
or
BMI = x KG / (y M * y M)


x=body weight in KG
y=body height in M

Example for 175 cm size and 70 kg weight:
BMI = 70 / (1,75 * 1,75) = 22,86

The resulting value is Kilogramm per Meter by the second or short KG/M2. In most cases this can be left. There is no really sense in this, because humans are no mathematical square. More about this also in BMI Criticism.

Tip for calculator:
If you try to use the formula in a hand calculator you get some problems. But with a little change it is be simple. So you can use:
weight / size / size
Example for 70 kg weight and 1,75 m size:
70 / 1,75 / 1,75 = 22,86

Step by step:

1.weight in kg
2./ (divided by)
3.size in m
4./ (divided by
5.size in m
6.=

you can give you height either in inches, centimeters and weight in pounds or kilograms.
After user clicks the calculate Button it will automatically calculate the BMI value for particular user and give the result.

This application is able to store the details of the BMI value results and if user is overweight it's give daily tips regarding your exercises and your recipies.
