Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h).

The term supersonic is used to describe a speed that is over the speed of sound (Mach 1). At a normal temperature like 70 degrees Fahrenheit (21.1 °C), the speed needed for something to be traveling at a faster than sound speed is about 344 m/s, 1,129 ft/s, 770 mph or 1,238 km/h.

May 19, 2009 · Supersonic includes speeds up to five times faster than the speed of sound, or Mach 5. In 1947, Air Force Capt. Charles E. “Chuck” Yeager became the first person to fly an aircraft faster than the speed of sound.
