Each of these tiny lines represents a fraction of an inch. There are five different lengths of lines in total. Each inch is divided into 16 lines, meaning that the space between each line is 1/16 inch long—this is the smallest length you can measure with a ruler.

What are the tiny lines in a ruler called?
The larger lines with numbers are centimeters, and the smallest lines are millimeters. Since millimeters are 1/10th of a centimeter, if you measure 7 marks after a centimeter, it is 1.7 centimeters long.
What are the small lines on a 12 inch ruler?
Between 0 and 1 inch, there are marks that denote 1/8, 1/4 (or 2/8), 3/8, 1/2 (or 4/8), 5/8, 6/8 (or 3/4), 7/8, and 1 (or 8/8) of an inch. In total, there are 96 of these marks on a 12 inch ruler.
What are the little lines on a mm ruler?
The distance between numbered marks on that side will be shorter than on the inches side, and the numbered marks will go as high as 30, because there are approximately 30 centimeters in 12 inches (the length of the standard ruler). The small lines between the larger, numbered lines represent millimeters.
What is smaller than inches on a ruler?
The inch is traditionally the smallest whole unit of length measurement in the imperial system, with measurements smaller than an inch being stated using the fractions 1/2, 1/4 , 1/8, 1/16, 1/32 and 1/64 of an inch.

Look at the unmarked lines on a metric ruler.
There are 2 separate units of measurements on a standard metric ruler—centimeters and millimeters. The numbered lines correspond to centimeters, while the unmarked lines indicate millimeters. If you look closely, you’ll notice that there are 10 millimeters in a centimeter.
What are the markers on a ruler?
Rulers are etched with markings that denote the measurement of distance. Every inch of a 12-inch ruler is marked out, and between each inch, every 1/8 of an inch or 1/16 of an inch is marked. Likewise, a ruler of a similar length measuring centimeters will have each of 30 centimeters marked out.
What are the little marks on a tape measure?
Metric tape measures feature 10 marks to the centimeter. The smallest marks on a tape indicate one millimeter or 1/10th of a centimeter. The large, bold markings on a metric tape measure indicate centimeters. The long mark in the center indicates a half-centimeter.
How long is a Millimetre?
The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre. There are ten millimetres in a centimetre.
