While working in laboratories, measurement of substances is an essential step. But of prime importance is the accuracy in measurements which is brought about by using accurate measuring apparatus. The accuracy of an apparatus is defined in terms of closeness of measured values to that of standard value. More is the closeness between the measured value and standard value; more will be the accuracy of the apparatus used.

The accuracy of an apparatus can be estimated from its least count as far as same apparatus is used. For example, if volume is measured graduated cylinders for different capacities, least count will govern the accuracy of their measurement. &nbsp;Least count is defined as the smallest value an instrument can measure. The smaller is the least count, more is the accuracy of measurement.

While measuring volumes by graduated cylinders, in general, smaller capacity cylinders are more accurate than the larger capacity cylinders as the least count of the latter is more.<ul><li>In case of 10 mL graduated cylinder, the graduation starts from a marking of 1 mL and there after the increment of graduation is 0.2 mL and so is its least count.</li><li>In case of 25 mL graduated cylinder, the graduation starts from a marking of 5 mL and there af...</li></ul>
