What is 1 millimeters long?

Small units of length are called millimeters. A millimeter is about the thickness of a plastic id card (or credit card). Or about the thickness of 10 sheets of paper on top of each other. This is a very small measurement! Meters can be used to measure the length of a house, or the size of a playground.

Which side of the ruler is CM?

The left side of the line where the object ends will be its measurement in centimeters. This way the line thickness will not affect the measurement.
