FAQ

What is the conversion factor from L/(min·m²) to gpm/ft²?
1 L/(min·m²) equals 0.02454301 gpm/ft². To convert, multiply the value in litres per minute per square metre (volumetric flux) by 0.02454301.
How do I convert 1 L/(min·m²) to gpm/ft²?
1 L/(min·m²) = 0.024543 gpm/ft². For any value, multiply by 0.02454301.
How do I convert gpm/ft² back to L/(min·m²)?
Divide by the same factor — or equivalently, multiply by 40.7448. So 1 gpm/ft² = 40.7448 L/(min·m²).
When would I need to convert litre per minute per square metre (volumetric flux) to US gallon per minute per square foot?
Volumetric-flux conversions between L/(min·m²) and gpm/ft² 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).
