The conventional classification of a physical quantity by its dependence on selected base quantities, independent of any chosen numerical unit.
wp-physics-physical_quantitybipm-si-brochureEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
A physical quantity is assigned dimensions relative to a chosen system of base quantities; the assignment is conventional but constrains valid products, powers, and equations.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

This is an authored directed relation from the source endpoint to the target endpoint.
Dimensional analysis uses the exponent vectors of quantity dimensions to test equations and organize independent dimensionless combinations under stated modeling assumptions.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
