• Answer:

  Usually rulers in the US will feature metric measurements on one side with the centimeters numbered, and imperical measurements on the other with the inches numbered. On the metric side the centimeters are about the width of your pinky. They are split into 10 usually (with smaller unnumbered marks), these are millimeters or tenths of a centimeter. A ruler is one foot long, or 12 inches (about the length of the end of your thumb). Inches are typically divided into halves, fourths, eighths and perhaps sixteenths with smaller and smaller markings. To measure something all you need to do is line up the end where 0(zero) would be before the one with one end of the thing you are measuring, if the thing you are measureing reaches out to the big 6 on the imperical side you know it is 6 inches long, or half of a foot. A protractor is similar. It works just like a small ruler on the bottom edge. The measurements on the curved side (0 through 180 with 90 at the top) are to measure angles, which I wont bother explaining unless you say you need to know that as well. Here is a good image that shows a ruler http://www.groz-tools.com/ruler.jpg you will note the twelve larger inches on the right side (broken up into sixteenths of an inch if you look closely, if the thing you measured reached the first small dash after the 6inch mark you would know that it is 6 and 1/16 inches.) and the 30 smaller centimeters on the left (there are ABOUT 30 centimeters in a foot)
