Jednostka

Jednostka is a Polish noun meaning unit. It is used in many domains to denote a single element of a set, a standard measure, or an organizational subdivision.

In measurement and science, a jednostka miary is a standard quantity used for measurement. In the SI system, the base units are meter (m), second (s), kilogram (kg), ampere (A), kelvin (K), mole (mol), and candela (cd). Additional units are derived by combining these.

In mathematics and logic, jednostka can refer to a unit element, the multiplicative identity in a ring or field, or to a unit vector. In Polish mathematical texts, the term is used similarly to the English “unit.”

In organizational and administrative contexts, jednostka denotes a distinct unit within a larger organization, such as a department, branch, or subdivision. In the military, jednostka wojskowa indicates a unit capable of independent operations. In public administration, jednostka samorządowa or jednostka organizacyjna describes an organizational unit.

In software and computing, test jednostkowy refers to a unit test in software testing, and moduł or jednostka may denote discrete components.

Commonly, the word is used generically to mean any singular item or entity within a broader system. The precise meaning depends on context.
