Question

We need an international standard unit of measuring length? Why or why not? ​

Answer 1

Answer:

We need a international standard unit of measurement because if we use pace or a footstep as standard unit of length as the size of foot and the footstep will not be same for every individual. Thus, the measurement will not be same for different people.
