kilometrów

Kilometrów is the genitive plural form of kilometr, the SI unit of length equal to 1000 meters. The term derives from the prefix kilo- meaning thousand and the unit meter, and it is used in Polish to express quantities of length in contexts where a numeral or determiner precedes the unit.

In Polish, when indicating a distance or amount measured in kilometers, the unit appears in the genitive plural after numerals or determiners, for example: sto kilometrów (one hundred kilometers), dwieście kilometrów, pięć tysięcy kilometrów. This form is standard in most measurements of distance, travel reports, and road signage when numbers are involved.

Kilometr as a unit is widely used for long distances and is commonly abbreviated as km. It is standard in everyday language, maps, road signs, and technical documentation. Speed is often given in kilometers per hour (km/h), and fuel consumption or travel time can be described using kilometers as the distance component.

In expressions of area, the phrase kilometrów kwadratowych is used to denote square kilometers, with kilometrów functioning as the genitive plural of kilometr and kwadratowych as the connected adjective. For example, a region might be described as having 1,500 kilometrów kwadratowych of area.

Overall, kilometrów represents how Polish grammatically marks quantities of kilometers in contexts where the unit is not the head noun, reflecting the standard use of the genitive plural after numerals.
