What Does Supersonic Mean?
At its core, supersonic refers to speeds greater than Mach 1, where Mach 1 equals the speed of sound. In practical terms, this translates to traveling faster than approximately 343 meters per second (or 1,125 feet per second) at sea level and at a temperature of 20 degrees Celsius (68 degrees Fahrenheit).
