FAQ
What is the conversion factor from cm/s to m³/m²/h?
1 cm/s equals 36 m³/m²/h. To convert, multiply the value in centimetres per second (volumetric flux) by 36.
How do I convert 1 cm/s to m³/m²/h?
1 cm/s = 36 m³/m²/h. For any value, multiply by 36.
How do I convert m³/m²/h back to cm/s?
Divide by the same factor — or equivalently, multiply by 0.02777778. So 1 m³/m²/h = 0.0277778 cm/s.
When would I need to convert centimetre per second (volumetric flux) to cubic metre per square metre per hour?
Volumetric-flux conversions between cm/s and m³/m²/h 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).
