Conversion formula

Forward

meters per second = Mach × 340.29

Reverse

Mach = meters per second × 0.002939

Example: 10 Ma × 340.29 = 3,402.9 m/s.

About both units

From

Mach

Mach is the ratio of an object's speed to the local speed of sound. Mach 1 at sea level in standard conditions = 1225 km/h (340.29 m/s). Supersonic starts at Mach 1; hypersonic at Mach 5. The Concorde cruised at Mach 2.04; the X-15 reached Mach 6.7.

Real-world: Concorde: Mach 2.04. F-16 fighter: Mach 2. SR-71 Blackbird: Mach 3.3. Space re-entry: Mach 25+.

Meter per Second

m/s

Metres per second (m/s) is the SI base speed unit. Used in physics, sports-science studies, and wind-speed reporting (e.g., hurricanes). Usain Bolt's 100 m sprint averaged 10.44 m/s. Hurricane-force winds are above 32.7 m/s.

Real-world: Usain Bolt's 100 m: avg 10.44 m/s, peak 12.27 m/s. Hurricane minimum: 32.7 m/s. Walking: 1.4 m/s.

Tips & common mistakes

Quick tips

Mach 1 = ~1225 km/h at sea level, standard conditions.
Local speed of sound decreases with altitude (colder air) — true Mach value varies.
Mach 0.8+ is "transonic"; Mach 1+ supersonic; Mach 5+ hypersonic.

Avoid these

Assuming Mach 1 is a fixed speed — depends on altitude and temperature.
Multiplying Mach values as simple ratios across altitudes.
Using Mach for subsonic everyday speeds — not practical.
