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.
Stage micrometer is a glass slide with a scale of known divisions used to calibrate the eyepiece micrometer. Ocular micrometer is a specialized eyepiece with a built-in scale used to measure the size of objects viewed under a microscope. They both help determine the magnification and size of objects but are used at different stages in the setup process.
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.
An ocular micrometer is a calibration tool used in microscopy to measure the size of objects in the field of view. It consists of a ruler etched onto a glass slide that fits into the eyepiece of a microscope. By comparing the size of objects to the known dimensions on the ocular micrometer, scientists can accurately measure the size of microscopic specimens.
The parts of a microscope that magnify the image include the objective lenses and ocular lens (eyepiece). The objective lenses are located at the lower end of the microscope and provide varying levels of magnification, while the ocular lens is at the top of the microscope and further magnifies the image produced by the objective lens.
The objective lens and the ocular lens both work together to increase the magnification in a microscope. The objective lens is responsible for gathering light and forming an initial image, while the ocular lens further magnifies this image for viewing.

1 ocular micrometer scale is equal to 1micrometer when it is seen from 10X objective it will be magnify by 100 times so, 1 ocular micrometer division become 0.1mm ( 1um * 100 = 0.1mm)
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.
it is because the objectives have different values of magnification.....

a tiny ruler that you know the measurements of, and you use it to calibrate the ocular lens of a microscope
Ocular micrometers are placed in the eyepiece of a microscope and have markings that are viewed alongside the specimen to measure its size. Stage micrometers are placed on the stage of a microscope and have known, predefined distances between markings used as a reference for calibrating the ocular micrometer. The graduations on an ocular micrometer may appear larger or smaller than those on a stage micrometer due to differences in magnification between the two.

The ocular is the upper lens and objective is the lower lens
Yes, a calibrated ocular micrometer can be used to measure the diameter or length of a field or object. Essentially, that is all that it is used for.
No, an ocular micrometer is used for measuring objects viewed through a microscope by comparing them to a scale etched onto the eyepiece. It is not designed to measure the diameter of a field of view.
