WANTED: Simple online calculator

[richkid]

hey guys..
im designing this site, and i need a calculator to make some simple area calculations.

The website is www.preventgraffiti.com and the information is on the order page. It is to simply allowing people to put in the area they need covered, and it will calculate how many litres of the product they will need.

I would prefer it in html if possible..but php if not.

I am open to offers, and looking at a quick result.

thanks
Tom
