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) = 0.000003037814718 Yard per Second (yd/s).

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.
Yard per second measures distance in yards traveled in one second.
1 yd/s = 0.9144 m/s = 3.29 km/h = 2.045 mph = 3 ft/s.
To ft/s: × 3. To m/s: × 0.9144. To mph: × 2.045.
Sprint speeds in track and field (10–12 yd/s for elite sprinters), projectile velocities, and some fluid flow measurements.
Usain Bolt peak: ~13.5 yd/s. NFL wide receiver sprint: ~11 yd/s. Baseball thrown: ~40–45 yd/s.
Confusing with ft/s — yd/s is 3× faster. Mixing up with mph.
1 yd/s = 3 ft/s = 0.9144 m/s. Multiply by ~2 to get approximate mph.
