An Introduction to the Laboratory

Calculation of Actual Size

The smallest space on this scale slide is equal to 0.1 mm


Use the Following Steps to Calculate the Correct Size

  1. Determine the diameter of the field of view using the scale slide
  2. Determine the number of cells needed to cross the field of view
  3. Divide the distance of the diameter by the number of cells needed
  4. The result is the size of a cell

The Above Calculation Using the Slides At The Top Of The Page

  1. 10 spaces x 0.1mm per space = field of view = 1.0 mm
  2. 3 cells across the diameter
  3. 1.0 mm diameter/3 cells
  4. About 0.33 mm per cell
