What are the examples of problems that may arise if standard units are not used?

Answer 1

Trade. If there were no standard units then you would have to learn which vendors used which units of measure. Perhaps you could take along some weight with you and say give me this much meat/potatoes etc. Buying liquids from one vendor might be $5/container but it's only $4/container somewhere else but are the containers the same size. Every city would have different units. Buying quantities of anything would be time consuming as you tried to figure out what quantity you were getting today.

Standard units came about for this reason. Trade between merchants, towns, farmers knew how much they were being paid for how much product. Initially these measures were still very much linked to individual cities or countries. Now measurements are generally well known and verifiable.

Answer 2

If standard units are not used, there can be confusion and errors in communication, calculations, and comparisons. It can lead to incorrect measurements, difficulty in sharing data with others, and potential safety risks in various fields such as science, engineering, and trade.

Answer 3

*No investigator could repeat, or evaluate or critique, the work of any other.

*There would be no way to check the value or accuracy of any scientist's work, and therefore no way to build on it or add to it.

*Actually, no scientist could accomplish much even by himself, because he could never evaluate the results of his own work. He could play around in his lab all he wanted, and would never know whether he had anything worth reporting.

*It's doubtful whether we would be out of caves yet.
