Mach number (Ma or M) is the speed of an object moving in air, divided by the speed of sound at that particular conditions, including temperature and pressure. For example, something traveling at Mach 5 is traveling at 5 times the speed of sound. DARPA officials said last week that the Aug. 11 test flight collected more than nine minutes of data during the entire mission. But when I search for how fast Mach 1 is, the number that almost always comes up is 767 mph. The drone was designed to reach Mach 20 -- or 20 times the speed of sound -- and could travel between Los Angeles and New York in just 12 minutes. The distance between Moscow and … A plane flying Mach 1.0 at sea level is flying about 1225 km/h (661 Knots, 761 mph), a plane flying Mach 1.0 at 30000 ft is flying 1091 km/h (589 knots, 678 mph) etc. The term “Mach” typically applies to planes, and it refers to the multiple of the speed of sound at which the plane is going through in a certain medium. The last category is hypersonic, which applies to aircraft that can exceed the speed of Mach 5 and can achieve speeds as high as Mach 10 (1,702–3,403 m/s; 6,126–12,251 km/h; 3,806–7,680 mph). 20.9 Rx in kmph.

At Standard Sea Level and temperature 15 degrees Celsius, the speed of sound is 761.2 miles per hour ( mph ) = 340.3 meters per second (m/s) = 1225 kph = 1116 foot per second (ft/s) = 661.5 knots (kn, kt or kts). The Subsonic regime is up to 609 mph while Transonic flight is achieved between 609 and 914 mph. Another independent review board will look into what went wrong with the second flight test in the coming weeks, DARPA officials said. 1. Conversion of units between 2,193 mph Mile Per Hour and Mach Number (2,193 mph mph and M) is the conversion between different units of measurement, in this case it's 2,193 mph Mile Per Hour and Mach Number, for the same quantity, typically through multiplicative conversion factors (mph and M). Virtually every time I read about the Lockheed SR-71 (including other threads on this forum), I see that its speed record is listed as approximately 2193 mph.The same blurb will invariably say this is "about Mach 3.3".

Here is one of the speed conversion : 20.9 kmph to mph. It launches on a rocket, then comes streaking back to Earth at enormous speeds, at times heating up to temperatures of nearly 3,500 degrees Fahrenheit. A superfast unmanned military plane traveled at 20 times the speed of sound and managed to control itself for three minutes before crashing into the Pacific Ocean in a recent test, military officials said. You will receive a verification email shortly. You are currently converting speed units from mach (speed of sound) to miles per hour 1 Ma = 760.5583392985 mph There was a problem. "An initial assessment indicates that the Flight 2 anomaly is unrelated to the Flight 1 anomaly," said Air Force Maj. Chris Schulz, DARPA HTV-2 program manager. Despite the problem, the aircraft reached speeds around Mach 20 (about 15,000 mph) and was able to control its flight for several minutes, officials said. Since sound travels at different speeds in different conditions, the calculations here are given for 20°C in dry air at sea level. Mach is a speed measurement based on the speed of sound. The speed of sound varies depending on many factors.
