Detailed explanation-1: -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.
Detailed explanation-2: -At 100x magnification you will be able to see 2mm. At 400x magnification you will be able to see 0.45mm, or 450 microns. At 1000x magnification you will be able to see 0.180mm, or 180 microns.
Detailed explanation-3: -Actual size = image size / magnification. Image size = magnification x actual size.
Detailed explanation-4: -Measure the scale bar image (beside drawing) in mm. Convert to µm (multiply by 1000). Magnification = scale bar image divided by actual scale bar length (written on the scale bar).
