SparkFun PCB Ruler - 12-Inch

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