What is the smallest ruler?
A ruler used for measuring very small lengths in an electron microscope was developed in 1994 by John McCaffrey and Jean-Marc Baribeau of the Institute for Microstructural Sciences at the National Research Council of Canada. The smallest division on the ruler is 18 atoms thick and individual atoms are visible.
What are the small lines in cm?
Each line represents 1 millimeter, which is equal to 1/10 or 0.1 cm (so 10 mm make up 1 cm). There will always be 10 lines from one centimeter to the next centimeter.

Does US customary ruler measure in inches or centimeters?
A ruler is an instrument used to measure small lengths. Often the calibrations are in customary units like inches and the metric units – centimetres and millimetres . If they are used to measure lengths while drawing on the desk and have calibrations of 30 centimetres (cm) or 12 inches (in), these are typically called scale rulers.
How are inches divided on a ruler?
How a standard ruler is divided up Name: Period: The standard ruler is broken up into even sections. The inch in broken up into halves, quarters, eighths, and sixteenths. You can tell what division each is by the length of the line. The smaller the division, the smaller the line is. The following figures show this break down.
What is a standard length of a ruler in cm?
