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.

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+.

Tips & common mistakes

Quick tips

1 cm/s = 0.01 m/s = 0.036 km/h.
Useful when m/s or km/h give awkward small numbers.
Use consistent metric prefixes to avoid confusion.

Avoid these

Treating cm/s as fast speeds.
Mixing cm/s with m/s in the same dataset without labels.
Converting improperly for wind or car speeds — wrong scale.

Frequently asked questions

How many Mach in a centimeter per second?
