Suppose length of an object is measured with a metre rod with least count equal to 0.1 cm. If the measured length of 62.5 cm, it has to be recorded as (62.5`pm`0.1) cm, stating the limits of error. Similarly, suppose time period of a pendulam is measured to be 2.0 sec, using a stopwatch of least count 0.1 sec, it has to be recorded as (2.0`pm`0.1) sec. It indicates that time period is in the range of 1.9 sec and 2.1 sec.
