gram is multiple and milligram is sub multiple of kilogram
They are related as they are parts of the same measurement unit: They are either whole kilograms or fractions of a kilogram, or both, as in 12kg 23gm.

Multiple and sub-multiples are used when the range of values is too large to be measured in a single unit.
· The multiples and sub multiples of mass are the Petagram, teragram, gigagram, megagram, kilogram, gram, milligram, microgram.AnswerAs the SI base unit for mass is the kilogram, the gram is the submultiple -not the other way around!
Some examples of units used to measure mass include kilograms (kg), grams (g), pounds (lb), and ounces (oz).

Unit for what? Masses are commonly given in kg., or in multiples of the Earth's mass. Distances are given either in km., or in astronomical units - that is, multiples of the average distance from Sun to Earth.Unit for what?

There are uncountably many of them, because the prefixes can go on for ever.
That probably refers to the SI prefixes, such as kilo (meaning 1000), mega (meaning a million), milli (meaning 1/1000), etc.
It isn't technically necessary; it is used for convenience, to avoid using very small or very large numbers.
There are smaller masses but they need not be submultiples.
mm,cm,m,kmA2, The Standard unit of length is the Metre. This can have applied the common multiples and sub-multiples, such as Mega and milli etc.
