To ft/s: ÷ 3,600. To mph: ÷ 5,280. To m/s: × 0.000085.
1 ft/h = 0.000085 m/s = 0.0003048 km/h = 0.3048 m/h.
For example, 1 Foot per Hour (ft/h) = 0.008466666667 Centimeter per Second (cm/s).

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.
Centimeter per second measures distance in centimeters traveled in one second. Common for small-scale movements and flows.
1 cm/s = 0.01 m/s = 0.036 km/h = 0.6 m/min.
To m/s: ÷ 100. To km/h: × 0.036. To mm/s: × 10.
Stream/river surface flow (10–200 cm/s), blood flow velocity in arteries (10–100 cm/s), small machine movements, and insect flight speeds.
Housefly speed: ~200 cm/s. Blood in aorta: ~40 cm/s. Small stream flow: 30–100 cm/s. Ant running: 1–3 cm/s.
Confusing cm/s with m/s — off by a factor of 100. Mixing up with mm/s.
100 cm/s = 1 m/s. Good for water flow, blood flow, and small animal speeds. Divide by 100 to get m/s.
