How do you read a metric ruler in inches?
Make sure you read the ruler from left to right. If you are measuring something, align it with the left side of the zero mark on the ruler. The left side of the line where the object ends will be its measurement in inches.
Is a metric ruler the same as a regular ruler?
In the United States, most rulers have the imperial measurements along one long edge while the other long edge shows the metric measurements. A standard ruler is 12-inches long and 30 centimeters in length. It is likely your ruler will state “inches” or “cm” to make it easier to tell which side is which.

How do you read cm and mm on a ruler?
On a metric ruler, the numbers represent centimeters. The individual lines between the numbers represent millimeters. Each millimeter is one-tenth of a centimeter, so ten millimeters equals one centimeter. Before you start measuring, make sure that one end of the object is lined up with the 0 cm mark on the ruler.
Which side of the ruler is metric?
Figure the centimeter measurement of the same shelf by counting the centimeters from the same end of the ruler you used for measuring in inches (the “0” point on the ruler is opposite for English and for metric—always on the left as you hold the ruler and look at the numbers you are measuring with).
What are the measurements of a ruler?
The markings on a standard ruler represent the fractions of an inch. The markings on a ruler from the start to the 1″ mark are: 1⁄16“, 1⁄8“, 3⁄16“, 1⁄4“, 5⁄16“, 3⁄8“, 7⁄16“, 1⁄2“, 9⁄16“, 5⁄8“, 11⁄16“, 3⁄4“, 13⁄16“, 7⁄8“, 15⁄16“, and 1”.

Is a millimeter big?
There are ten millimetres in a centimetre. One millimetre is equal to 1000 micrometres or 1000000 nanometres. Since an inch is officially defined as exactly 25.4 millimetres, a millimetre is equal to exactly 5⁄127 (≈ 0.03937) of an inch.
