Question

Difference between multiple and submultiple​

Answer 1

Answer:

multiple is the product of any quantity and an integer. ... This terminology is also used with units of measurement (for example by the BIPM and NIST), where a submultiple of a main unit is a unit, named by prefixing the main unit, defined as the quotient of the main unit by an integer, mostly a power of 10^3.

Answer 2

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.
