There are usually scales on the ruler to measure the length. Some rulers have a special shape such as a letter or a circular hole in the middle, which is convenient for the user to draw pictures. They are usually used to measure and calculate the length. They are generally divided into tape measure, vernier caliper, square ruler, and straight edge.
