Formula

Formula
m³/m²/s = in/min × 0.0004233333

Multiply any value in inches per minute (volumetric flux) by 0.0004233333 to obtain the value in cubic metres per square metre per second.

Worked example

Convert 1000 in/min to m³/m²/s.

  1. 01Start with 1000 in/min.
  2. 02Multiply by the conversion factor: 1000 × 0.0004233333 = 0.423333 m³/m²/s.
Result1000 in/min = 0.423333 m³/m²/s

FAQ

What is the conversion factor from in/min to m³/m²/s?
1 in/min equals 0.0004233333 m³/m²/s. To convert, multiply the value in inches per minute (volumetric flux) by 0.0004233333.
How do I convert 1 in/min to m³/m²/s?
1 in/min = 0.000423333 m³/m²/s. For any value, multiply by 0.0004233333.
How do I convert m³/m²/s back to in/min?
Divide by the same factor — or equivalently, multiply by 2362.205. So 1 m³/m²/s = 2362.2 in/min.
When would I need to convert inch per minute (volumetric flux) to cubic metre per square metre per second?
Volumetric-flux conversions between in/min and m³/m²/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).
