Mach = centimeters per second × 2.9387e-5

Example: 10 Ma × 34,029 = 340,290 cm/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+.

Centimeter per Second

cm/s

Centimetres per second (cm/s) is used for slow-moving phenomena — ocean currents, earthworms, biological cell motion. Typical ocean surface currents: 10–100 cm/s. Continental drift: about 2–10 cm/year (converted: very slow cm/s).

Real-world: Gulf Stream: 100–200 cm/s. Amoeba: 1 mm/s = 0.1 cm/s. Sediment settling: 0.01–1 cm/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.
