How to convert mach to centimeters per second
1 Mach = 34,300 cm/s, so multiply by 34,300 to go from Mach (at 343 m/s) to centimeters per second. Going the other way, 1 cm/s = 2.91545189504 × 10⁻⁵ Mach.
cm/s = Mach × 34,300 Mach = cm/s × 2.91545189504
Worked example:
1 Mach = 34300 cm/s 5 × 34300 = 171500 cm/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).
- Centimeters per Second (cm/s)
- Centimeters per second, a metric unit. Definition: BIPM SI Brochure, 9th edition (SI units, prefixes and units accepted for use with the SI).
