क्यों एक माप की जरूरत दोनों एक संख्या है और इसके पूरा विनिर्देश के लिए एक इकाई करता है

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
