Ocular micrometers are see-through disks with a ruler in them that go in the eypiece of a microscope to measure what you are seeing. Stage micrometers are put on the stage/view platform of the microscope, so instead of putting them in the eyepiece you are putting them right next to the object you are looking at in the microscope.

The ocular micrometer is inside the ocular lens, it will not change size when the objectives are changed. Therefore, each objective lens must be calibrated separately. Ocular micrometers have no units on them - they are like a ruler with marks but no numbers. In order to use one to measure something under a microscope, you must assign numbers to the marks. This is done by looking through your OCULAR micrometer at a STAGE micrometer mounted on a slide. The stage micrometer is just a ruler with fixed known distances, so you can use it to tell how far apart marks are on the ocular micrometer. This has to be done because the marks on the ocular micrometer are different distances apart depending on the magnification used on the microscope. It must be calibrated for each objective.

It is necessary to superimpose the two scales and determine how many of the graduations coincide with one graduation on the scale of the stage micrometer.

Two divisions of the stage micrometer is equal to 20 micrometers. 20 micrometers/13 = 1.54micrometers You multiply this by 16 to find the diameter of the cell. 1.54 x 16 = 24.62 micrometers
