600km

600 kilometers (600 km) is a length in the metric system. A kilometer equals 1,000 meters, so 600 km equals 600,000 meters. In miles, 600 km is about 372.8 miles. The term is widely used in geography, transport, and logistics to describe distances on Earth.

Geographic distances of this magnitude commonly appear as regional separations within large countries or between nearby regions. In road travel, a steady 100 km/h would cover 600 km in about six hours, subject to traffic, terrain, and stops; at highway speeds around 120 km/h, the time would be closer to five hours. In air travel, direct flights of roughly 600 km often take about one hour to an hour and a half, depending on aircraft performance and wind conditions. High-speed rail can cover similar distances in roughly two to three hours, depending on the route and technology.

Uses: The 600-km figure is convenient for planning travel itineraries, evaluating logistics networks, and comparing transport options. It also appears in energy and emissions analyses, driving-range estimates for vehicles, and educational contexts that illustrate large-scale distances.
