One ruler to rule them all. This is a basic 12 inch ruler, but made from a PCB. We have included a lots of useful information on each side of the ruler that you might use on a daily basis including Wire Gauge holes, transistor diagrams, common fractions, Roman numerals, and metric to imperial conversions. Most importantly, the ruler provides you with a straight line and centimeter markings one side and inch markings on the other side.
You'll also find a small protractor in the middle for all your angle measurement needs. While we figured you have a fairly good idea how to use a ruler we do have a tutorial to explain all the information you'll see!
