# How fast is mach 3 in meters per second?

Mach 3 = **1,020.87 meters per second.**

### How fast is mach 10?

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

### How fast is 20 mach in mps?

That's a tough question to answer, because the speed of sound depends on altitude, and you haven't specified any. Mach 20 = 20 times the speed of sound. At sea level: Speed of sound = 343 meters per second. Mach 20 = (343 x 20) = 6,860 meters per second = 4.263 miles per second = 15,345 miles per hour.

### How fast is mach 1.6 in MPH?

Mach refers to a measure of speed, equivalent to the speed of sound. As such, because the speed of sound increases as the temperature increases, Mach 1 is not a constant measure. At a temperature of 15 degrees celsius, the speed of sound is equal to 340.3 metres per second. Therefore, Mach 1.6 at 15 degrees Celsius is equal to 340.3 x 1.6 = 544.48 metres per second.
