Simple BMI Form

This is the home page for TopCode’s Simple BMI Form plugin.

There are many BMI widgets in the plugin directory, but none offer a choice of 3 systems of units.

The BMI calculation is a simple formula:
BMI = your-weight / your-height squared

Wikipedia is used to categorise different BMI values.

What makes this calculator different is that its multi-national – site visitors can choose whichever system of units they are familiar with.
