Rendered to 6 significant figures.
Formula
Formula
Mach = m/s × 0.00293867
Multiply any value in metres per second by 0.00293867 to obtain the value in Mach (sea level, 15 °C).
Worked example
Convert 343 m/s to Mach.
- 01Start with 343 m/s.
- 02Multiply by the conversion factor: 343 × 0.00293867 = 1.00796 Mach.
Result343 m/s = 1.00796 Mach

FAQ
What is the conversion factor from m/s to Mach?
1 m/s equals 0.00293867 Mach. To convert, multiply the value in metres per second by 0.00293867.
How do I convert 1 m/s to Mach?
1 m/s = 0.00293867 Mach. For any value, multiply by 0.00293867.
How do I convert Mach back to m/s?
Divide by the same factor — or equivalently, multiply by 340.29. So 1 Mach = 340.29 m/s.
When would I need to convert metre per second to Mach (sea level, 15 °C)?
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).
