Volumetric Flux

LMHtoL/(min·m²)

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

Factor1 LMH = 0.01666667 L/(min·m²)

Converter

LMH

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

Result
1L/(min·m²)

Rendered to 6 significant figures.

Formula

Formula
L/(min·m²) = LMH × 0.01666667

Multiply any value in litres per square metre per hour by 0.01666667 to obtain the value in litres per minute per square metre (volumetric flux).

Worked example

Convert 60 LMH to L/(min·m²).

  1. 01Start with 60 LMH.
  2. 02Multiply by the conversion factor: 60 × 0.01666667 = 1 L/(min·m²).
Result60 LMH = 1 L/(min·m²)

FAQ

What is the conversion factor from LMH to L/(min·m²)?
1 LMH equals 0.01666667 L/(min·m²). To convert, multiply the value in litres per square metre per hour by 0.01666667.
How do I convert 1 LMH to L/(min·m²)?
1 LMH = 0.0166667 L/(min·m²). For any value, multiply by 0.01666667.
How do I convert L/(min·m²) back to LMH?
Divide by the same factor — or equivalently, multiply by 60. So 1 L/(min·m²) = 60 LMH.
When would I need to convert litre per square metre per hour to litre per minute per square metre (volumetric flux)?
Volumetric-flux conversions between LMH 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).
