How to calculate cell size with magnification

WebSize of the cell Use a ruler to measure the diameter of the red blood cell in the center of the above micrograph. This is 30 mm. Convert this number to micrometers. This is equal to 30,000 μm. We already know the magnification is 4,500x. Rearrange the magnification equation to find the actual length of the red blood cell. 4500 Drawing a scale bar Web7 jun. 2024 · Divide the field number by the magnification number. For instance, if the eyepiece is labeled as 30x/18, then 18 ÷ 30 = 0.6, meaning that the diameter of for is 0.6 millimeters. For microscopes that only have an eyepiece, this will be enough. But having an objective lens as well makes the calculation harder.
