What are the basic prefixes used in the metric system and how do they relate to the size of the base unit?

The metric system is based on a system of tens so all the units in the system relate to each other in terms of tens. To the basic unit: 1000 milli = [unit] 100 centi = [unit] 10 deci = [unit] 0.1 deca = [unit] 0.01 hecto = [unit] 0.001 kilo = [unit]
