What Is This Tool?
This converter transforms speeds measured in Cosmic velocity - third, which is the escape velocity needed to leave the Solar System, into the more widely used kilometer per second (km/s) unit. It supports space mission design and celestial mechanics by expressing complex velocities in familiar terms.
