Meter per Second (m/s)
The metre per second (m/s) is the SI unit of velocity. As a face velocity it equals a volumetric flow of 1 m³/s through 1 m² of area.
Symbol: m/s
Quantity: face velocity and air permeability (volumetric flow per unit area)
SI relation: m/s is the coherent SI unit of face velocity & air permeability.
Derivation: 1 m/s = 1 m ÷ 1 s (equivalently 1 m³/s of flow per 1 m² of area)
Exact: yes, by definition
Typical uses
- Filter face velocity (ISO 16890 full-size filters ≈ 2.7 m/s)
- Fume hood and biosafety cabinet face velocity (≈ 0.4–0.5 m/s)
- Duct and coil air velocity
- Cleanroom unidirectional airflow (≈ 0.45 m/s)
