Formula
Formula
m/s = Mach × 340.29
Multiply any value in Mach (sea level, 15 °C) by 340.29 to obtain the value in metres per second.
Worked example
Convert 2 Mach to m/s.
- 01Start with 2 Mach.
- 02Multiply by the conversion factor: 2 × 340.29 = 680.58 m/s.
Result2 Mach = 680.58 m/s

FAQ
What is the conversion factor from Mach to m/s?
1 Mach equals 340.29 m/s. To convert, multiply the value in Mach (sea level, 15 °C) by 340.29.
How do I convert 1 Mach to m/s?
1 Mach = 340.29 m/s. For any value, multiply by 340.29.
How do I convert m/s back to Mach?
Divide by the same factor — or equivalently, multiply by 0.00293867. So 1 m/s = 0.00293867 Mach.
When would I need to convert Mach (sea level, 15 °C) to metre per second?
Velocity conversions are needed for fluid flow analysis (line velocity targets, erosional limits), gas-stream calculations, and equipment specs that mix m/s, ft/s and engineering speed units.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
