Formula

Formula
in/min = L/(min·m²) × 0.03937008

Multiply any value in litres per minute per square metre (volumetric flux) by 0.03937008 to obtain the value in inches per minute (volumetric flux).

Worked example

Convert 100 L/(min·m²) to in/min.

  1. 01Start with 100 L/(min·m²).
  2. 02Multiply by the conversion factor: 100 × 0.03937008 = 3.93701 in/min.
Result100 L/(min·m²) = 3.93701 in/min

FAQ

What is the conversion factor from L/(min·m²) to in/min?
1 L/(min·m²) equals 0.03937008 in/min. To convert, multiply the value in litres per minute per square metre (volumetric flux) by 0.03937008.
How do I convert 1 L/(min·m²) to in/min?
1 L/(min·m²) = 0.0393701 in/min. For any value, multiply by 0.03937008.
How do I convert in/min back to L/(min·m²)?
Divide by the same factor — or equivalently, multiply by 25.4. So 1 in/min = 25.4 L/(min·m²).
When would I need to convert litre per minute per square metre (volumetric flux) to inch per minute (volumetric flux)?
Volumetric-flux conversions between L/(min·m²) and in/min 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).
