ქიმიის ტერმინთა განმარტებითი ლექსიკონი

Quantity in a conventionally chosen subset of a given system of quantities, where no subset quantity can be expressed in terms of the others.

Note 1: The subset mentioned in the definition is termed the „set of base quantities“. Example: The set of base quantities in the International System of Quantities (ISQ).

Note 2: Base quantities are referred to as being mutually independent since a base quantity cannot be expressed as a product of powers of the other base quantities.
