25kilometre

25kilometre is a stylized label used to denote a distance of 25 kilometres. It is not an official SI unit; standard usage writes the distance as 25 kilometres or 25 km. One kilometre equals 1,000 metres, so 25 kilometres equals 25,000 metres, about 15.532 miles.

The term appears most often in branding, signage, or informal writing where a single word is preferred. In professional contexts, however, the two-word form or the abbreviated form 25 km is preferred to avoid ambiguity. The concept of a 25-kilometre distance is common in planning and navigation, for example when describing a catchment radius around a city center, a service area for logistics, or the length of a cycling or running route.

In sport and recreation, many races and routes use nonstandard distances such as 25 kilometres, making 25 kilometres a recognizable length even if not a standard race distance. As with other kilometre-based labels, the exact interpretation depends on context, but the numerical value remains 25,000 metres. See also Kilometre, Mile, Distance measurements.
