Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
The A380 has a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude), its maximum design speed is Mach 0.96.
Mach is not an absolute speed but a relative speed. The Mach value of an object is the ratio of the speed fo the object travelling through a medium to the speed of sound travelling through the same medium. Now sound travels faster in denser mediums so the speed of sound in [dense]air at sea level is greater than the speed of sound at high altitude. So Mach 2 in the air at sea level is faster than Mach 2 at high altitude. But Mach 2 under water is very much faster. However, most people are ignorant about the proper meaning of Mach and assume that it is simply related to the speed of sound at sea level at normal temperature/pressure/humidity - approximately 760 miles per hour. In that case Mach 8 would be 6080 mph.
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
Mach 1 is 761.21 mph.Use this equation to convert Mach to miles per hour: mach x 761.21 = mph
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
2,608.72 miles per hour.
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
750*0.82=615 mph By the way, 1 mach is the speed of sound, which is 750 mph
The A380 has a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude), its maximum design speed is Mach 0.96.
Mach one is the speed of sound, which is about 761.2 miles per hour (340.3 meters per second). Mach two is twice the speed of sound, which is about 1,522.4 miles per hour (680.6 meters per second).
Mach refers to the speed of sound in air. Typically about 750 mi/hr but it varies faster or slower with temperature from cold to hot respectively. Mach one is one times speed of sound. Mach 3 would be three times speed of sound.
Mach 24 is roughly equal 18,264 miles per hour. Mach is a term used to describe the ration of the speed of an object to the speed of sound. The speed of sound, at sea level, is roughly 761 mph. Mach 24 means that the ration of the speed of an object to the speed of sound is 24, meaning 24 times the speed of sound. Thus, at sea level, an object travelling at mach 24 is travelling at 24 times 761mph, which is 18,264 miles per hour.
Mach 10 is equivalent to 3,402.9 meters per second. It is about 7,000 miles per hour. At Mach 10, an aircraft could circumnavigate the earth in less than four hours. The Mach number is a measure of how fast an object is travelling relative to the speed of sound. The Mach number is calculated by dividing the speed of an object by the speed of sound. Speed of sound is about 760mph

The absolute top speed remains classified. Officially "in excess of Mach 3" Probably closer to Mach 3.5 - 3.8
