Question
Answer the following in detail.
Explain in detail why there was a need to standardize units.
Solution
The traditional units were not uniform as the length of a cubit, foot and handspan varied from person to person according to their body size. Similarly, there was no certainty that all grains were exactly the same weight. So these units could not be used for scientific measurements where accuracy was a prime concern. The development of a large number of systems of measurement also made it very difficult to conduct trade and commerce between different societies. Therefore, people felt the need to have standard units that could be used for accurate measurement and were accepted universally.
