Question

It is not proper to measure quantities by using body parts as units.
​

Answer 1

Answer:

It is not proper to measure quantities by using body parts as units because these are not reliable and unique. These units of measurement vary from person to person. ... So, it becomes necessary to get the weights and measures standardized at regular intervals

Answer 2

Explanation:

It is not advisable to use our body parts for measuring quantities because each and every individual's body parts are of different shapes and sizes. Measurment of an object may vary if you use body parts which will lead to confusion.

This is why the French had come up with the international unit of measurement (the metric system) to which every country agreed.

The USA, however, uses the imperial system as their unit of measurement.
