Base units of measurement in the SI system are the fundamental units used to express physical quantities, and they are defined based on the laws of physics.

A unit multiple is a unit that is a power of 10 times larger than the base unit, used to express larger quantities.
Unit prefixes are used to denote multiples and submultiples of a unit, such as kilo- for 10^3 and milli- for 10^-3.

A derived unit is a unit that is derived from the base units through multiplication, division, or other mathematical operations.
A coherent derived unit is a derived unit that can be expressed as a product of powers of the base units, without any numerical factor other than 1.

Unit prefixes are used to denote multiples and submultiples of a unit, such as kilo- for 10^3 and milli- for 10^-3, and they are used to simplify the notation and expression of physical quantities.
