Volumetric Flux

in/mintoL/(min·m²)

Convert inches per minute (volumetric flux) (in/min) to litres per minute per square metre (volumetric flux) (L/(min·m²)).

Factor1 in/min = 25.4 L/(min·m²)

Converter

in/min

Accepts numbers or expressions, e.g. 150 + 14.7

Result
25.4L/(min·m²)

Rendered to 6 significant figures.

Formula

Formula
L/(min·m²) = in/min × 25.4

Multiply any value in inches per minute (volumetric flux) by 25.4 to obtain the value in litres per minute per square metre (volumetric flux).

Worked example

Convert 1 in/min to L/(min·m²).

  1. 01Start with 1 in/min.
  2. 02Multiply by the conversion factor: 1 × 25.4 = 25.4 L/(min·m²).
Result1 in/min = 25.4 L/(min·m²)

FAQ

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