I created a body mass index calculator the other day.
It has a special feature. If you place a link to it on your website or blog, and click on that link, you will see a link back to your site on the results pages.
This calculator is one of few that gives results for kids without referring you to a chart.
It also allows the user to enter data in feet, inches and pounds or centimeters and kilograms.
Here is the link:BMI Calculator
