1 kilometer (km) = 1000 meters (m)
1 milometer (mm) = 1000 micrometers
1 micrometer = 1000 nanometers

Calculating Magnification

You multiply the the magnification of the eye piece by the magnification of the objective lense e.g. 4x10 = x40 magnification

Calculating image size under a microscope

Magnification = size of image/size of real object.
example:
if you're working at magnification x40 and the image is 1mm you can work out the actual size:

size of real object = size of image/magnification
so
1/40mm = 0.025mm or 25 micrometers

light microscope vs electron microscope

light microscopes have a max magnification of around x2000 vs electron microscope is x2,000,000

light microscopes are smaller and cheaper vs electron microscopes which are larger and more expensive

light microscopes have a resolution of around 2000nm vs
