Unit System

Physical units should be in the metric system when possible. Contributions that are not in line with this recommendation should be converted into the metric system.

Images

Images can be found at Wikimedia Commons.

Instructions on how to include images from Wikimedia Commons are found here.

If you wish to produce your own illustrations but do not have a professional tool to work with, I suggest you try out Inkscape. The program is excellent and free.

Automatic Indexing

Don't forget to add the tag {{BookCat}} at the bottom of each page. This will include the page in wikibook.org's indexing system.
