because most objects viewed are so small that millimeters are to big to measure with.
According to wikipedia, these are Gram-positive bacteria that appear round and form clusters like grapes when viewed under a microscope.
Perimeter is a concept that applies to 2 dimensional objects. With most 3 D objects it makes no sense because for anything other than a sphere, the answer depends on the perspective: where the shape is being viewed from..In this case of the car, do you mean a bird's eye view? or a view of the car from the front or from a side? These are the plan, front and side elevations and any one of them is a measure of the "extent" of the car. In addition, there are angular aspects which will give other results.
No If you have a picture of it you can use the measurements you know to give you the scale of the picture. Or if you don't have a picture you can use the length of your thumb viewed at arms length, and then calibrate using a known object, or better still, the known width.

The field of view measurements are in micrometers. The abbreviation looks like a "u" and an "m"
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.
Objects that are smaller than the wavelength of visible light cannot be viewed in a compound microscope. This includes objects such as individual atoms or molecules.

Objects appear magnified and clearer when viewed through a light microscope due to the lenses that focus light to create an enlarged image. The microscope allows for detailed examination of the specimen's structure and features not visible to the naked eye. The use of specialized stains or dyes can enhance contrast and visibility of specific parts of the object being observed.

This process is called calculating the field of view diameter on a microscope. It involves measuring the diameter of the field of view using a ruler and knowing the magnification of the objective lens to determine the actual size of objects viewed under the microscope.
The working distance of a stereo microscope refers to the distance between the objective lens and the specimen. A longer working distance allows for larger objects to be viewed, as there is more space between the lens and the specimen. Conversely, a shorter working distance limits the size of objects that can be viewed due to the physical constraints of the microscope's design.
Things that are too small for a light microscope, such as viruses and molecules, can be viewed using an electron microscope. Electron microscopes use a beam of electrons instead of light to magnify objects at a much higher resolution than light microscopes.
Opaque objects do not let light pass through them, so they block the light needed for the microscope to form an image. This prevents the microscope from capturing a clear image of the object. As a result, opaque objects appear dark and featureless when viewed under a light microscope.
