FAQ
What is the conversion factor from m³/m²/h to gfd?
1 m³/m²/h equals 589.0322 gfd. To convert, multiply the value in cubic metres per square metre per hour by 589.0322.
How do I convert 1 m³/m²/h to gfd?
1 m³/m²/h = 589.032 gfd. For any value, multiply by 589.0322.
How do I convert gfd back to m³/m²/h?
Divide by the same factor — or equivalently, multiply by 0.0016977. So 1 gfd = 0.0016977 m³/m²/h.
When would I need to convert cubic metre per square metre per hour to US gallon per square foot per day?
Volumetric-flux conversions between m³/m²/h and gfd 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).
