Meaning of Micrometry:
Micrometry is the science in which we have some measurement of the dimensions of an object being observed under the microscope. The method employs some special types of measuring devices which are so oriented that these can well be attached to or put into the microscope and observed. The object, to be measured, is calibrated against these scales.
Once we are observing an object under a microscope by the 5X objective and the 10X eyepiece we say that the image that we are able to perceive is 5 × 10 = 50 times of the object.
