Question

Why ancient methods of measurement are not preferred for taking measurements?

Answer 1

Ancient methods of measurement use body parts for taking measurements. As different people have different shapes and sizes of their body parts, the ancient units of measurement vary from person to person. These methods can't be used to measure half or a quarter of some length accurately. Also, people in different regions of the world had their own units, which created confusion in trade and commerce. Due to these reasons, ancient methods of measurement are not preferred for taking measurements.
