What is the importance of calibration of ocular micrometer?
Basically, calibration is the “zero” setting on a measuring object. For example a weighing scale that is incorrectly calibrated would, for example, read 50 pounds as 49 pounds. This means that whatever is actually on the scale would be one pound heavier than what it actually is. This is not a problem when comparing two things of different weight (the difference will be the same) but if you are measuring something as a single unit, it could be troublesome. An ocular micrometer is what’s on microscopes and basically tells you how big an object is. An incorrectly calibrated micrometer would be catastrophic since a small difference in the reading could have a massive effect on what you’re trying to do. For example, a 2mm difference could mistakenly read a 300% increase in bacteria growth. Another reason is that calibrations set the standard for what is what. For example, you should be able to measure a pencil with a ruler as 4.2 inches then take another ruler and it would ALSO read 4.2 inc
