Question

How are the submultiple units of length are related to the parent unit

Answer 1

The SI unit of lenght is metre. When a larger distance is to be covered,we cannot use metre. So to cover a larger distance we use km(kilometre) , hm (hectometre) , and dac(decametre). These are called the multiples of Metre. When the distance is smaller , we use Dm (decimetre , cm(centimetre) and mm (millimetre) . These are called the submultiples of Metre.
