On the imaged example, each square is 0.05 mm wide, and each line represents 0.01 mm, making the diameter of the field of view 0.55 mm in this case. Thus, you can calculate the area in mm<sup>2</sup> by Googling: | |||

Sometimes "high power field" (HPF) is used for area, but it has a substantially different area for different microscopes, for example: | Sometimes "high power field" (HPF) is used for area, but it has a substantially different area for different microscopes, for example: | ||
