761.2 mph at sea level, though it will vary depending on temperature and atmospheric composition.
Mach 1 is the speed of sound, approximately 768 miler per hour, but it will vary based on density of air, caused by humidity.
The unit Mach doesn't have a direct conversion to mph, because Mach 1 is the speed of sound (Mach 2 is 2 times the speed of sound etc.) and the speed of sound changes with altitude, while mph stay the same regardless of altitude and therefore causes the conversion between the two units to vary. For example, at sea level the speed of sound is 761.2 mph, but at 18 miles of altitude the speed of sound is 673.4mph. Got to the following webpage for a table of the speed of sound (Mach 1) at different altitudes.
Mach 1 or any other Mach number, is not a specific speed.
Mach numbers refer to the speed of sound in that medium.
Mach 1 is about 760 mph at sea level (+ or - 4-5 degrees depending on the temperature). Mach 1 decreases as you go to higher elevations.
At 30000 ft Mach 1 is 678 mph (589 knots, 1091 km/h) which is about cruising altitude for an average commercial airplane. (1 knot=1.15078 mph / 1 mph=0.868976 knots)
At what density altitude? Speed of sound slows with altitude. 761.05 mph at sea level on a normal day(60 degrees F, 29.92 barometric press.)
It changes with weather, atmospheric conditions and altitude. Most accept 657 miles per hour at 10,000 as the speed of sound.

How fast is Mach .88 in mph?
There is no finite answer to this, since the term Mach (the speed of sound through air or water) changes based on the temperature of the air itself. In 60 deg F air at sea level, Mach 1 is 761mph. In dry air at 68 deg F, mach 1 is 768 mph. Mach 1.4 is 1.4 x these speeds. Usually Mach speeds are used for objects travelling in air, but not always. Mach 1 in water is 4.3 times faster than air and Mach 1 in iron is 15 times faster than air.
How fast is mach 3 in meters per second?
Mach 3.6 = 2,740.34 mph
How fast is 79 mach in mph?
This is the rough formula. Mach = velocity/speed of sound This is rough because conditions are truly variable, but............ 79 Mach = velocity/768 mph = ~606070 miles per hour
How fast is mach 2.02 in mph?
Twice the speed of sound. That's the definition of mach number.Mach number is a more useful measurement of speed than miles per hour in some ways (especially if you're designing an airplane), but not so good for answering questions like "So when are we getting to Denver?" since the speed of sound varies depending on the density of the air.the actual speed of mach 2 is 2472 km/h which is twice mach 1 (1236km/h) at this speed the airplane is roughly 2 meters shorter. planes that can travel this fast are;e111-a ravenmig 25 foxbatf22- raptorf22- strike raptoryf 12a blackbirdconcordef 35 c
What does mach 3 mean in aeronautics?
2283.6211 miles per hour is considered as mach 3. To be able to reach Mach 1 is to go 761.207 miles per hour. It is used to measure the speed of aircraft and rocketry.
What mph is Mach 3?
Mach 3 is 2283.6211 mph because Mach 1 equals 761.207033 mph.
How fast is mach 20 in mph?
Mach 1 is about 762 mph, so mach 20 is about 15,240mph.
How do you calculate mach into mph?
The way you calculate mach into mph, is you type it into the calculator and it will tell you the answer! Now go do it....
How many mph is mach1?
Mach 1 is about 761.2 mph
How fast is mach 5 in mph?

What is a mach vs a mile per hour?
Mach 1 is 761.21 mph
What is meant by machnumber?
Mach is a measure of speed based on the speed of sound at sea level. Mach 1 = 642 MPH . Mach 2 = 2 x 642 MPH or 1284 MPH.

How many miles per hour does 0.791 mach equal?
mach 1 = 761.207 mph, so 761.207 * 0.791 = 602.115 mph
How fast in mph is mach 3?
Mach 3 means flying three times the faster than sound. Speed of sound at an usual temperature is 346m/s. This means Mach 3 is about 1 km/s. That is 3600kmph. That is 2250 mph.2283.59 mph
