Centimeter per Second (cm/s)
The centimetre per second (cm/s) is one hundredth of a metre per second. A flow of 1 cm³/s through 1 cm² gives exactly 1 cm/s.
Symbol: cm/s
Quantity: face velocity and air permeability (volumetric flow per unit area)
SI relation: 1 cm/s = 0.01 m/s (exact)
Derivation: 1 cm/s = 0.01 m ÷ 1 s = 1 cm³/(s·cm²)
Exact: yes, by definition
Same quantity as milliliter per second per square centimeter (mL/(s·cm²)) , cubic centimeter per second per square centimeter (cm³/(s·cm²)) : the factor between them is exactly 1.
Typical uses
- Filter media testing (5.33 cm/s = 32 L/min through 100 cm²)
- ASTM D737 metric results in cm³/(s·cm²)
- Settling and diffusion velocities
