How to Convert Mach to Feet per Second
Converting Mach (mach) to feet per second (ft/s) involves using the speed of sound. Mach 1 is defined as the speed of sound, which is approximately 1125.33 feet per second at sea level and 20°C.
Formula
Feet per Second = Mach × 1125.33
or
ft/s = mach × 1125.33
Step-by-step process
- Take the measurement in Mach
- Multiply that number by 1125.33
- The result is the equivalent amount in feet per second
Examples
- 1 mach = 1125.33 ft/s
- 10 mach = 11253.3 ft/s
- 0.5 mach = 562.665 ft/s
When to Convert Mach to Feet per Second

Frequently Asked Questions
How many feet per second are in one Mach?
One Mach is approximately 1125.33 feet per second (at sea level, 20°C).
Why is the conversion factor 1125.33?
The speed of sound varies with temperature and medium. At sea level and 20°C, the speed of sound in dry air is approximately 343 meters per second. Since 1 ft/s = 0.3048 meters per second, then 343 / 0.3048 ≈ 1125.33 ft/s.
