Why Learn to Read a Metric Ruler?

Reading a ruler is a valuable skill that you will likely use on your job, in your hobbies, and in your personal every day life. Without measuring devices like rulers (and people who can read them) we would still be living in caves.

The metric ruler is divided into millimeters (or millimetres). Ten millimeters is a centimeter (or centimetre). Ten centimeters is a decimeter (or decimetre). Ten decimeters is a meter (or metre).

Although you are probably familiar with rulers, meter sticks, tape rules, folding rules, and tape measures, you will also find rulers on many machines that you use such as saws, sewing machines, photocopiers, and computer scanners. Computer programs like Microsoft Word and Adobe PhotoShop have electronic rulers that you can turn on to help you with the exact placement of items. Reading a ruler is a valuable skill that you will use almost every day, both on and off the job.
