Speed Converter

Speed measures how fast an object moves over a given distance in a unit of time. It is essential in many fields: transportation for setting vehicle and aircraft speeds, sports for tracking athletic performance, physics for studying motion and dynamics, and navigation for calculating maritime and aerial travel times.

Different contexts use different speed units: the metric system uses meters per second (m/s) and kilometers per hour (km/h), while the imperial system relies on miles per hour (mph) and feet per second (ft/s). In maritime and aviation, knots (kn) are the standard, and in aeronautics, Mach numbers express speed relative to the speed of sound.
