Answer» To MEASURE any physical quantity, we compare it with a standard (UNIT) of that quantity. No measurement is perfect as the errors INVOLVED in the process cannot be removed completely. Hence, in SPITE of our best effort, the measured value of a quantity is always somewhat different from its actual value, or TRUE value.
