How to Convert Centimeter per Second to Foot per Second Manually
Step by StepConverting centimeters per second to feet per second is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.
- 1Take your value in centimeters per secondStart with the number of centimeters per second (cm/s) you want to convert.
- 2Multiply by 0.032808The conversion factor from cm/s to ft/s is 0.032808. Multiply your value by this number.
- 3Read the result in feet per secondThe result is your value in feet per second (ft/s).
Formula
Multiply the value in centimeters per second by 0.032808. For the reverse direction, multiply by 30.48.
ft/s = cm/s × 0.032808cm/s = ft/s × 30.48Tips
Use these in everyday conversions- 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.
Common Mistakes
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.
About Centimeter per Second and Foot per Second
What is the Centimeter per Second?
Centimeters per second is the natural unit for slow, sustained motions: ocean currents, biological growth rates, sedimentation in geology, and laboratory fluid dynamics. The Gulf Stream flows at about 90–250 cm/s, glaciers creep at 1–10 cm/s on average, and fingernails grow at roughly 0.0035 cm/s. Centimeters per second appears in oceanography, hydrology, soil science, and biological motion studies. It relates to m/s (100 cm/s = 1 m/s), km/h (1 cm/s = 0.036 km/h), and mph (1 cm/s ≈ 0.0224 mph). The CGS (centimeter-gram-second) unit system used cm/s as its base speed, which influenced older physics literature, particularly in astrophysics and fluid mechanics.
- Ocean current speeds
- Biological motion (cells, small organisms)
- Laboratory fluid flow rates
Gulf Stream: 100–200 cm/s. Amoeba: 1 mm/s = 0.1 cm/s. Sediment settling: 0.01–1 cm/s.
What is the Foot per Second?
Feet per second is the standard ballistics unit for projectile speeds, American sports analytics, and engineering. Bullet velocities are universally given in fps: a .22 LR bullet flies at about 1,200 fps, a 9 mm pistol round at 1,150 fps, and a high-velocity rifle round at 3,000 fps. American football and baseball analytics increasingly use fps for measuring throwing speed, ball exit velocity, and player movement. Engineering disciplines that retain US customary units (HVAC, civil engineering) often specify air or water flow speeds in fps. The unit relates to mph (1.467 fps = 1 mph), m/s (1 fps ≈ 0.305 m/s), and the knot (1 fps ≈ 0.592 kn). Outside ballistics and US sports, m/s and km/h dominate — but in their domains, fps remains entrenched in American technical practice.

9mm bullet muzzle velocity: ~1150 ft/s. .308 rifle: ~2700 ft/s. Free fall terminal velocity: ~195 ft/s.
