About Gigameters

A gigameter (Gm) is one billion meters (10⁹ m), making it useful for planetary measurements and inner solar system distances. The Sun's diameter is about 1.39 Gm, while Jupiter's diameter is roughly 0.14 Gm. The distance from Earth to the Moon is approximately 0.38 Gm. This unit bridges the gap between terrestrial measurements (megameters) and astronomical distances, providing a convenient scale for describing planetary sizes and nearby celestial distances in our solar system.

About Kilometers

A kilometer (km) is 1,000 meters and the standard unit for measuring longer distances in most of the world. It takes about 10-12 minutes to walk one kilometer at a normal pace. Common references include: a typical city block might be 100-200 meters (0.1-0.2 km), most cars display speed in km/h, and marathon races are 42.195 kilometers long. Road signs, GPS systems, and maps globally use kilometers to indicate distances between cities and locations.
