How to convert meters per second to mach

1 Mach = 343 m/s, so divide by 343 to go from meters per second to Mach (at 343 m/s) (1 m/s = 0.00291545189504 Mach).

Mach = m/s ÷ 343
m/s = Mach × 343

Worked example:

1 m/s = 0.00291545189504 Mach
5 × 0.00291545189504 = 0.0145772594752 Mach

About the units

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).
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).
