The measurement of a given quantity is essentially an act or result of comparison between the quantity (whose magnitude is not known) and a predefined standard.

As both quantities are compared, the result is expressed in numerical values. To achieve a significant result, we basically need the following:-

  • The standard used for the comparison purposes should be accurately defined and commonly accepted.
  • The apparatus used and the method adopted must be provable.


Importance of measurement

The advancement of Science and Technology is dependent upon a parallel progress in the measurement techniques. It will not be wrong to say that the quickest way to assess an organization or a nation’s progress in Science and Technology is to examine the type of measurement that is being made, used and processed.

As Science and Technology move ahead, new phenomena and relationships are discovered and these advances make new types of measurement necessary. All new discoveries are of no practical utility unless they are backed up by actual measurement. The measurement no doubt, confirm the validity of a hypothesis but also add to its understanding. This results in an unending chain, which leads to new discoveries that require more, new and sophisticated measurement techniques.

Hence modern Science and Technology are associated with sophisticated methods of measurement while elementary Science and Technology require only ordinary methods of measurements.

There are two major parts of engineering:

  • Design of equipment and processes.
  • Proper operation and maintenance of equipment and processes.

Both these functions require measurement. This is because proper and economic design, operation and maintenance require feedback of information. This information is supplied by making suitable measurement.
