1. TOPIC: Microscope AIM: How is a specimen viewed with a microscope measured?

2. Micrometers Microns µm = um 1mm = 1000µm What unit is used to measure
cells?
Micrometers
Microns
µm = um
1mm = 1000µm

3. Paper thickness =
about 150 µm

4. Human hair diameter = µm

5. SHRIMP EGGS

6. Multiply by 1000 or simply move the decimal 3 places to the right.
mm  µm

7. Example:
3.2 mm = ? µm

8. 0.7634mm = ? µm 
763.4 µm

9. Move the decimal three places to the left or divide by 1,000
µm mm
Move the decimal three places to the left or divide by 1,000

10. Example:
789 µm = ? mm 
0.789 mm

11. 53.6 µm = ? mm  mm

12. Smaller to larger =
move decimal to left
um  mm
Larger to smaller =
move decimal to the right
mm um
