How do you read a ruler?

Answer 1

Reading a Ruler is very easy. This is only if you are using whole numbers for inches and centimeters. here are a few easy steps on how we can read the ruler.

1. There are 2 different measurement systems in rulers. English and Metric. If you don't find the sides to be labelled, its easy to make out which side is inches and which side is centimeters just by looking between the lines.

2. Now if you watch it, you will find 9 lines between each centimeter that make up one millimeter. So naturally 10 millimeters would make up a centimeter. This is useful in terms of metric calculation.

3. If its inches, the number of lines would be seven instead of 9. So depending on what system you want to use is makes up your reading of the ruler. If you are using Metrics, use centimeters or if you use English, use inches.

4. When starting to measure, see that your start and end points are perfectly placed. Also take note of the points. The later point is what makes up the measurement.

5. Suppose you end up on not a whole number, say you are using centimeters as preferred choice of measurement i.e metric system. You start to measure and you end up at a non whole number such as 5 lines after 3 number, then your measurement would be 3.5 centimeters i.e 3 centimeters and 5 millimeters.
