Specimens are measured in microns (µm)!
1 millimeter = 1000 microns (micro meters)
If this caterpillar is 20mm long, how many microns is it?
(20mm)(1000) = 20,000 microns
Which magnification will show more space, 40X or 100X?
40X40X will show more than 100X
Ruler at 40X
How many mm across?3mm
How many microns across?
3,000 µm
3 X 1000 = 3,000 µm across
How many millimeters? Microns?
High power magnification
Low power magnification=

(40)(3mm) = (400)(X)
120mm = 400X

0.3mm=
How many microns is that?
0.3mm X 1000 = ?
300 µm
If the field of view is 600 microns across, how far across is one specimen?
If you can fit 6 across 600 microns, how far across is one circle?
Diameter / # of objects
600 microns/6 circles = 100 microns each
