Where can I find a Body Mass Index calculator online?

[JonnyBoy12]

Can anyone tell me how a person's B.M.I. is calculated? If so are there any online calculators for this, and if so do they accept data in both Metric and Imperial scales as well? Hope you will be able to answer this, as need to know this for Paraxel trials in the next day or 2. You could save me a wasted trip all the way to London, if I can get this information now.

Thanks in advance for any replies.
