Question

why were the past methods of measuring physical quantities inaccurate​

Answer 1

Answer:

Unfortunately, measurement is never 100% precise or accurate, so the true value measure of something is never exactly known. This uncertainty is a result of error. Error is a concept that is naturally associated with measuring because measurement is always a comparison to a standard.
