Why are the units of measurement standardized?

Answer 1

This is done in order to keep a complete medium of relativity. If a kilogram becomes "roughly a kilogram" then 100 kilograms becomes "between 95 and 105 kilograms", so on and so forth until macro calculations become impossible.

In keeping a strict standard, there is no doubt left between mediums. This is also why calibrations are important in that any two devices need to be able to keep the same measurements, be it a scale, speedometer, etc.

Answer 2

Standardized units of measurement ensure consistency and accuracy in communication and comparison of quantities across different places and times. It allows for easy understanding and collaboration in various fields such as science, engineering, and trade.

Answer 3

If units where never standardized, each unit could have many different values. For example, If we didn't have a universal standardization for time a second could last a year or a day.
