Convert Meters per Second to Centimeters per Second

Formula

cm/s = m/s × 100

Derivation from SI units:

• 1 m/s = 1 m ÷ 1 s (equivalently 1 m³/s of flow per 1 m² of area)
• 1 cm/s = 0.01 m ÷ 1 s = 1 cm³/(s·cm²)

Both units are defined exactly, so the factor is exact. Meter per Second definition: meter per second; Centimeter per Second definition: centimeter per second.

Worked examples

1. 0.0533 m/s is 5.33 cm/s, the usual media velocity for flat-sheet filter testing.
   0.0533 m/s × 100 = 5.33 cm/s
2. A cleanroom downflow of 0.45 m/s is 45 cm/s.
   0.45 m/s × 100 = 45 cm/s

Where it's used

Low velocities in m/s are converted to cm/s for filter-media and respirator testing, where results are quoted at a fixed face velocity such as 5.33 cm/s.
