[Calculating Drawing Magnification of Microorganisms Viewed Through the Microscope]

a. The actual size of the beastie at lower left is estimated to be 200 µm.

b. The drawing at lower right is measured to be about 6 cm long. Convert this to µm, which is about 6000 µm long.

c. Divide the drawing length by the actual size of the organism

In this case: 60000 µm / 200 µm = 300 X

The drawing is 300 times larger than the actual organism!
