Formula

Formula
cm/s = m³/m²/h × 0.02777778

Multiply any value in cubic metres per square metre per hour by 0.02777778 to obtain the value in centimetres per second (volumetric flux).

Worked example

Convert 36 m³/m²/h to cm/s.

  1. 01Start with 36 m³/m²/h.
  2. 02Multiply by the conversion factor: 36 × 0.02777778 = 1 cm/s.
Result36 m³/m²/h = 1 cm/s

FAQ

What is the conversion factor from m³/m²/h to cm/s?
1 m³/m²/h equals 0.02777778 cm/s. To convert, multiply the value in cubic metres per square metre per hour by 0.02777778.
How do I convert 1 m³/m²/h to cm/s?
1 m³/m²/h = 0.0277778 cm/s. For any value, multiply by 0.02777778.
How do I convert cm/s back to m³/m²/h?
Divide by the same factor — or equivalently, multiply by 36. So 1 cm/s = 36 m³/m²/h.
When would I need to convert cubic metre per square metre per hour to centimetre per second (volumetric flux)?
Volumetric-flux conversions between m³/m²/h and cm/s are routine in membrane filtration (RO, UF, MF, NF permeate flux), hydraulic loading specification, water-treatment design, hydrometallurgy and packed-bed column loading, and environmental engineering. LMH (L/m²/h) and gfd (gal/ft²/day) dominate membrane datasheets; m³/m²/h and m³/m²/day cover SI engineering ladders; m/day and cm/s appear as superficial velocity in hydromet and packed-bed work. Volumetric flux is the same physical quantity as superficial velocity (m³/m²/s ≡ m/s) but is kept distinct from the velocity and flow categories because the engineering intent is volumetric throughput per unit area, not bulk motion or total throughput.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
