This toolbox item shows the units used in microscopy and the formula for calculating the magnification of a drawing.
I. Units for measurement:
Due to the extremely small size of some samples, the unit for measuring is the micrometer (µm)
1 m |
= |
1 000 mm |
|
|
|
|
1 mm |
= |
1000 µm |
=>
|
1 µm |
= |
1/1 000 mm |
1 m |
= |
1 000 000 µm |
=>
|
1 µm |
= |
1/1 000 000 mm |
II. Line aid for metric conversion
400 m |
=
|
400 000 mm |
=
|
400 000 000 µm |
50 µm |
=
|
0.05 mm |
=
|
0.005 cm |
450 cm |
=
|
4 500 mm |
=
|
4 500 000 µm |
1 200 µm |
=
|
1.2 mm |
=
|
0.12 cm |
8 cm |
=
|
80 mm |
=
|
80 000 µm |
