To define: an exact quantity that people agree to use to compare measurements.

Expert Solution & Answer
Check Mark

Explanation of Solution

Introduction:

In order that the people in different parts of world may compare the results of their experiments on a constant basis, it is necessary to define certain standard units of length, weight, time, temperature and electrical, quantities. The magnitude of the measured quantity is expressed in terms of a chosen unit with the same quantity standard.

For example a length can be measured in terms of meter and a numerical constant. Therefore a length of 10 meters indicates a length 10 times longer than a meter. Therefore, the magnitudes of the various units may be preserved using standard. They will use this standard as a guide for reference.

Conclusion:

Hence, the same number of quantities that people use to equate is a standard quantity.
