    how do you remember the formula?

    also, how do you convert micrometers to mm and what would the units be for the answer if you used mm in all your calculations?

    magnification = size of image / size of object

    because if you magnify an object by 2, you get an image that is twice the size of the object (therefore magnification is x2)

    there are 1000 micrometers in a millemeter

    A way to remember it is to think about what happens when you're magnifying something v small - the magnification is a large number, eg x2000; therefore magnification = "big number"/"small number", and as Revenged mentions the "big number" is going to be the size of the image, while the "small image" will be the actual size of the structure.
