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. (Note that some rulers only go down to 1/8 inch lines, whereas others go down to 1/32 inch lines.)

What are the lines called on a ruler?
hash marks
A ruler or measuring tape can be used to measure lengths in both metric and customary units. Here, the ruler is marked in centimeters (cms) along the top and in inches along the bottom. The marks or intervals on a ruler are called hash marks.
What are the lines on a inch 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”.
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 are the lines on a tape measure?
Standard tape measure markings
The lines are different sizes – the smaller the line, the smaller the measurement. For instance, the inch marks are the largest lines and the sixteenths of an inch are the smallest. Inches are generally the easiest measurement to read on a tape measure.
How do you count the marks on a ruler?
Locate the zero end of the ruler, and then count each individual mark along the edge of the ruler. Each mark represents 1 millimeter or mm, so counting five marks is the same as counting 5 millimeters, counting 10 marks is the same as counting 10 millimeters and so on.
How many lines are on a ruler?

What does a ruler measure in science?
A metric ruler is the standard instrument for measurement in the scientific laboratory. On a metric ruler, each individual line represents a millimeter (mm). The numbers on the ruler represent centimeters (cm). There are 10 millimeters for each centimeter.
What is the first line in mm ruler?
Remember that when measuring a length with a ruler, we start from the first line on the left of the ruler, which is the zero line. The two red lines marked are one millimetre apart. Since this is the first line we come to after 0, it is 1 mm.
What is 1.5 mm on a ruler?
MM, CM to inches conversion table

What are rulers kids?
A ruler (or ‘rule’) is an instrument of measurement. Rulers measure length. Length is how long or short something is. Most rulers work by having numbers (parallel to the measuring edge) and little lines (perpendicular to the measuring edge). Rulers can also be used as a straight edge to draw lines with.
