Microscopy & measurement Calculators
Magnification, scale bars, field-of-view density and surface-area-to-volume calculations used throughout practical biology.
Magnification & actual size
Calculate magnification, image size or actual size with automatic mmāĀµmānm conversion and full working.
Open calculatorScale bar actual size
Use a micrograph scale bar to calculate actual specimen size without relying on the displayed magnification.
Open calculatorField-of-view density
Estimate cell or stomatal density from a count within a circular microscope field of view.
Open calculatorSurface area : volume
Calculate surface area, volume and SA:V ratio for cubes, spheres and cylinders.
