To m/s: ÷ 360,000. To m/h: × 0.01. To mm/h: × 10.
1 cm/h = 0.01 m/h = 0.00001 km/h = 0.00000278 m/s. Extremely small speed unit.
For example, 1 Centimeter per Hour (cm/h) = 0.03280839895 Foot per Hour (ft/h).

Centimeter per hour measures very slow movements in centimeters over an hour. Used for extremely gradual processes.
1 cm/h = 0.01 m/h = 0.00001 km/h = 0.00000278 m/s. Extremely small speed unit.
To m/s: ÷ 360,000. To m/h: × 0.01. To mm/h: × 10.
Very slow geological processes, material expansion/contraction measurements, and some biological growth studies.
Human nail growth: ~0.01 cm/h. Stalagmite formation: ~0.001 cm/h. Some coral growth: 0.1 cm/h.
Using for anything except very slow processes. Confusing with cm/min or cm/s.
100 cm/h = 1 m/h. Primarily a scientific measurement unit. Not for everyday use.
Foot per hour measures distance in feet traveled over one hour. Used for very slow movements in imperial units.
1 ft/h = 0.000085 m/s = 0.0003048 km/h = 0.3048 m/h.
To ft/s: ÷ 3,600. To mph: ÷ 5,280. To m/s: × 0.000085.
Glacier movement in US studies, very slow industrial processes, and some geological measurements.
Some glaciers move at 50–500 ft/h. Very slow conveyor systems might use this unit.
Confusing with ft/min (60× faster) or ft/s (3,600× faster).
5,280 ft/h = 1 mph. Extremely slow. Rarely used outside specialized contexts.
