Question

Why does a measurment need both a number'
and a'unit' for its complete Specification​

Answer 1

Answer:

A measurement needs both a number and a unit for complete specification because : If we just say 6, the other person will not understand what we mean; hence we have to use a unit of length. If we just say metres, the person will wonder how many metres; therefore we have to tell the number to express the right quantity.
