Answer 2

You can remember the prefix and the conversion factor that it corresponds to:
centi - 0.01
deca - 10
kilo - 1000
milli - 0.001
and so on. It'll be easy to remember conversions if you can commit them to memory.

Answer 5

What I meant was that each prefix states the conversion factor with respect to the SI base unit.
For example, 1 centimetre = 0.01 metres
1 decametre = 10 metres and so on.
