What is a good website to go and download a copy of the periodic table on one side and the metric conversion system on the other...you know like the one's they pass out to students during a major test.

The first one is the periodic table. The second one is the SI system of prefixes.

I don't know one that gives both. I suspect your profs have obtained the information from two sources, then recopied them on front and back of paper.
