The width of a wooden block recorded by two students as 5.25 cm and 5.27 cm are equally precise.

  • The precision of an observed value tells to what resolution the quantity is measured.
  • So, if the measured values are very close to each other, they are precise. An instrument that gives a tight cluster of repeated results is a precise instrument.
  • The least count of a measuring instrument is the smallest quantity by which it is capable of measuring.
  • Since the smallest unit of the ruler is 1 mm, it is called the least count of the ruler and can also be written as 0.1 cm.
  • The values recorded by the two students are the same upto the one-tenth place and hence, they are said to be precise.
