Formula

Formula
L/(min·m²) = m³/m²/day × 0.6944444

Multiply any value in cubic metres per square metre per day by 0.6944444 to obtain the value in litres per minute per square metre (volumetric flux).

Worked example

Convert 1440 m³/m²/day to L/(min·m²).

  1. 01Start with 1440 m³/m²/day.
  2. 02Multiply by the conversion factor: 1440 × 0.6944444 = 1000 L/(min·m²).
Result1440 m³/m²/day = 1000 L/(min·m²)

FAQ

What is the conversion factor from m³/m²/day to L/(min·m²)?
1 m³/m²/day equals 0.6944444 L/(min·m²). To convert, multiply the value in cubic metres per square metre per day by 0.6944444.
How do I convert 1 m³/m²/day to L/(min·m²)?
1 m³/m²/day = 0.694444 L/(min·m²). For any value, multiply by 0.6944444.
How do I convert L/(min·m²) back to m³/m²/day?
Divide by the same factor — or equivalently, multiply by 1.44. So 1 L/(min·m²) = 1.44 m³/m²/day.
When would I need to convert cubic metre per square metre per day to litre per minute per square metre (volumetric flux)?
Volumetric-flux conversions between m³/m²/day 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).
