Formula

Formula
m³/m²/day = LMH × 0.024

Multiply any value in litres per square metre per hour by 0.024 to obtain the value in cubic metres per square metre per day.

Worked example

Convert 100 LMH to m³/m²/day.

  1. 01Start with 100 LMH.
  2. 02Multiply by the conversion factor: 100 × 0.024 = 2.4 m³/m²/day.
Result100 LMH = 2.4 m³/m²/day

FAQ

What is the conversion factor from LMH to m³/m²/day?
1 LMH equals 0.024 m³/m²/day. To convert, multiply the value in litres per square metre per hour by 0.024.
How do I convert 1 LMH to m³/m²/day?
1 LMH = 0.024 m³/m²/day. For any value, multiply by 0.024.
How do I convert m³/m²/day back to LMH?
Divide by the same factor — or equivalently, multiply by 41.66667. So 1 m³/m²/day = 41.6667 LMH.
When would I need to convert litre per square metre per hour to cubic metre per square metre per day?
Volumetric-flux conversions between LMH and m³/m²/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).
