Calculation of Actual Size: To calculate the actual size of a magnified specimen, the equation is simply rearranged: Actual Size = Image size (with ruler) ÷ Magnification.

How do you find the actual size of a specimen microscope?

Estimating the Size of the Specimen Under Observation



To estimate the size of an object seen with a microscope, first estimate what fraction of the diameter of the field of vision that the object occupies. Then multiply the diameter you calculated in micrometers by that fraction.

How do you calculate the actual size of a cell?

Divide the number of cells that cross the diameter of the field of view into the diameter of the field of view to figure out the length of one cell. If the diameter of the field is 5mm and you estimate that 50 cells laid end to end will cross the diameter, then 5mm/50 cells is 0.1mm/cell.

How do you find the actual size of an object?

Video quote: It by the number of specimens get they can fit completely across the the field of view. So the size of the object is equal to the field of view divided by the fit number and it's that simple.
