MacGyver Tip: Quick paper ruler

MacGyver Tip: Quick paper ruler: "

The dollar bill isn't the only quick ruler on the block. The Transuranic blog shows us how you can use a standard piece of letter paper (8.5" x 11") to make a quick and accurate foot-rule.

Take the first page, and fold from either top corner down to the side, lining up the side carefully, making a right triangle.

Remember how you thought you'd never use trig? Well you were right, because I just used it for you. One ABC and three squares later, the hypotenuse of the right triangle you've created is 12.02 inches - very close to being exactly one foot.

Quick and easy, and a .02" margin of error is good enough for me. Give it two more folds and you've got markers for 3", 6", and 9" as well.
