Question

why does a measurement need both a number and a unit for its complete specification
​

Answer 1

Answer:

Explanation:

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.

Answer 2

$\huge\mathbb{ANSWER:-}$

• Measurement need both a 'number' and a 'unit' for its complete specification as the former number tells us as to how many times does unit get contained in the length to be measured.
