Volumetric Flux

cm/hrtoL/m²/day

Convert centimetres per hour (volumetric flux) (cm/hr) to litres per square metre per day (L/m²/day).

Factor1 cm/hr = 240 L/m²/day

Converter

cm/hr

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

Result
240L/m²/day

Rendered to 6 significant figures.

Formula

Formula
L/m²/day = cm/hr × 240

Multiply any value in centimetres per hour (volumetric flux) by 240 to obtain the value in litres per square metre per day.

Worked example

Convert 1 cm/hr to L/m²/day.

  1. 01Start with 1 cm/hr.
  2. 02Multiply by the conversion factor: 1 × 240 = 240 L/m²/day.
Result1 cm/hr = 240 L/m²/day

FAQ

What is the conversion factor from cm/hr to L/m²/day?
1 cm/hr equals 240 L/m²/day. To convert, multiply the value in centimetres per hour (volumetric flux) by 240.
How do I convert 1 cm/hr to L/m²/day?
1 cm/hr = 240 L/m²/day. For any value, multiply by 240.
How do I convert L/m²/day back to cm/hr?
Divide by the same factor — or equivalently, multiply by 0.004166667. So 1 L/m²/day = 0.00416667 cm/hr.
When would I need to convert centimetre per hour (volumetric flux) to litre per square metre per day?
Volumetric-flux conversions between cm/hr and L/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).
