Mach 1 is equal to about 741 miles per hour. Mach is the ratio of an object's speed to the speed of sound. For example, something traveling at Mach 5 is traveling at 5 times the speed of sound. The speed of sound varies depending on many factors. In dry air, at 0 degrees Celsius, the speed of sound is about 331.3 meters per second.

By definition, at Mach 1, the local flow velocity u is equal to the speed of sound. At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic).

Mach to Miles per hour (Mach to mph) conversion calculator for Speed conversions with additional tables and formulas.

Mach 1 is equal to 767.269148 miles per hour, so use this simple formula to convert: miles per hour = Mach number × 767.269148. The speed in miles per hour is equal to the Mach number multiplied by 767.269148. For example, here's how to convert Mach 2 …

It is equal to exactly 1.609344 kilometers per hour. How many miles per hour are in a Mach? Use this easy and mobile-friendly calculator to convert between Mach and miles per hour. Just type the number of Mach into the box and hit the Calculate button.

Convert any Mach value to Miles-Per-Hour using the conversion calculator below. NOTE: As Mach values are largely temperature-dependent (outside air), the end-value presented above is representative of an object traveling at sea-level (15C / 59F).

2021年5月13日 · As the speed of the object approaches the speed of sound, the flight Mach number is nearly equal to one, M = 1, and the flow is said to be transonic. At some places on the object, the local speed exceeds the speed of sound.

Use the conversion factor: 1 mach equals 761.207 miles per hour. For example, to convert 1 mach to mph, calculate 1 x 761.207 mph , which is 761.207 mph . The formula is: speed in mph = speed in mach x 761.207

2024年1月12日 · Consequently, Mach 1 is equal to the local speed of sound, that is the speed in the medium through which an object is traveling. The local nature of the measure might make it seem...

By definition, Mach number is a ratio of the speed of a body (aircraft) to the speed of sound in the undisturbed medium through which the body is traveling. It is said that the aircraft is flying at Mach 1 if its speed is equal to the speed of sound in air (which is …
