What does 40x mean on a microscope?

How to calculate the magnification of an image?
Actual Length = length of the Image divided by the Magnification. Magnification = length of the Image divided by the Actual Length. Magnification can be calculated using a scale bar. This is a line drawn near the photograph or drawing which has a label showing the actual length of the bar before being magnified. Convert to µm (multiply by 1000).
How to record the magnification of the ocular lens?
To do this, record the magnification of the ocular lens in the eyepiece and record the magnification of the objective lens (these numbers are usually engraved on the sides of both types of lenses). Next, multiply the ocular lens magnification by the objective lens magnification.
