Ultrastructure Size Calculator
A slide-guide-calculator used to determine the real-life size of a structure from a micrograph- in micrometer, nanometer or angstrom units. It computes the real-life dimension/mm at magnifications from 1,000 to 100,000 by introducing a multiplication factor of x2 or x1/2. The magnification range can be extended.
