Question

What are some disadvantages of using old unit systems for measurement?

Answer 1

Answer:

Explanation:

1. In some sense they are less arbitrary than earlier systems of measurement which were based on specific (and sometimes temporary) standards, they are still arbitrary in their magnitudes. For example, the meter is defined in terms of an arbitrarily chosen fraction of the distance light travels in one second. That fractional distance corresponds approximately to one ten-millionth of the distance from the Earth’s pole to its equator.

2. One of them is defined in terms of a prototype (viz. the kilogram) although work is ongoing to fix that problem.
