How to convert centimeters per second to mach

1 Mach = 34,300 cm/s, so divide by 34,300 to go from centimeters per second to Mach (at 343 m/s) (1 cm/s = 2.91545189504 × 10⁻⁵ Mach).

Mach = cm/s ÷ 34,300
cm/s = Mach × 34,300

Worked example:

1 cm/s = 2.91545189504e-5 Mach
5 × 2.91545189504e-5 = 0.000145772594752 Mach

About the units

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).
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).
