Centimeter per Second to Mile per Hour

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.

Mile per hour measures how many statute miles are traveled in one hour. It's the primary speed unit in the United States and some other countries using imperial measurements.

1 mph = 0.44704 m/s = 1.609 km/h. The conversion factor comes from the statute mile definition.

To km/h: × 1.609. To m/s: × 0.447. To ft/s: × 1.467. To knots: × 0.869.

US speed limits (25 mph residential, 65–75 mph interstate), vehicle speeds in US/UK, hurricane wind speeds (74+ mph), and baseball pitch speeds.

Sound barrier: 767 mph at sea level. Fastest car: 282.9 mph (Koenigsegg). Commercial jet: 550–580 mph cruise. Cheetah: 70 mph sprint.

Assuming 1 mph ≈ 1 km/h — actually 1 mph ≈ 1.6 km/h. Also, confusing statute miles with nautical miles.

Quick conversion: multiply mph by 1.6 for approximate km/h. Remember: 60 mph ≈ 100 km/h (slightly off but close).
