How do I calculate magnification for my microscope?

It’s very easy to figure out the magnification of your microscope. Simply multiply the magnification of the eyepiece by the magnification of the objective lens.

The magnification of both microscope eyepieces and objectives is almost always engraved on the barrel (objective) or top (eyepiece). Look for numbers like 10x, 12.5x, etc.
