Rendered to 6 significant figures.

Formula

Formula
m/day = LMH × 0.024

Multiply any value in litres per square metre per hour by 0.024 to obtain the value in metres per day (volumetric flux).

Worked example

Convert 100 LMH to m/day.

  1. 01Start with 100 LMH.
  2. 02Multiply by the conversion factor: 100 × 0.024 = 2.4 m/day.
Result100 LMH = 2.4 m/day

FAQ

What is the conversion factor from LMH to m/day?
1 LMH equals 0.024 m/day. To convert, multiply the value in litres per square metre per hour by 0.024.
How do I convert 1 LMH to m/day?
1 LMH = 0.024 m/day. For any value, multiply by 0.024.
How do I convert m/day back to LMH?
Divide by the same factor — or equivalently, multiply by 41.66667. So 1 m/day = 41.6667 LMH.
When would I need to convert litre per square metre per hour to metre per day (volumetric flux)?
Volumetric-flux conversions between LMH and m/day 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).
