How to convert mach to meters per second
1 Mach = 343 m/s, so multiply by 343 to go from Mach (at 343 m/s) to meters per second. Going the other way, 1 m/s = 0.00291545189504 Mach.
m/s = Mach × 343 Mach = m/s × 0.00291545189504
Worked example:
1 Mach = 343 m/s 5 × 343 = 1715 m/s

About the units
- Mach (Mach)
- Mach (at 343 m/s), a specialised unit. Mach 1 is the local speed of sound, which depends on air temperature; this converter uses 343 m/s (dry air at 20 °C). In the standard sea-level atmosphere (15 °C) it is 340.3 m/s. Definition: Speed of sound in dry air at 20 °C: 343 m/s (NASA Glenn Research Center).
- Meters per Second (m/s)
- Meters per second, a metric unit. Definition: BIPM SI Brochure, 9th edition (SI units, prefixes and units accepted for use with the SI).
