The kilogram is not a base unit, the gram is.Additional AnswerYes, you are quite correct, the kilogram is the only SI base unit with a prefix. The above answer is unfortunately incorrect.
Yes, the kilogram is the SI base unit for mass. Fun fact: the kilogram is the only SI base unit with a prefix.
Adding a prefix changes the magnitude of the base unit. The prefix indicates a multiple of 10 by which the base unit is multiplied. Common prefixes include milli- (0.001), kilo- (1000), and mega- (1,000,000).
This is because the gram is too small for most practical applications.
The prefix for volume is "milli-" which represents one thousandth of the base unit.
Centi
Because they indicate the relationship of the unit to the base unit
dec-(i think)
The metric prefix for 10 is deka-. This is similar (but different) from the metric prefix for 1/10 which is deci-
Kilo- is the unit of the metric system that represents 1000 times the base unit.
In the metric system, "centi" is a prefix: it is not a measurement unit of any kind.
