in/mintocm/hr

1 in/min equals 152.4 cm/hr. To convert, multiply the value in inches per minute (volumetric flux) by 152.4.

1 in/min = 152.4 cm/hr. For any value, multiply by 152.4.

Divide by the same factor — or equivalently, multiply by 0.00656168. So 1 cm/hr = 0.00656168 in/min.

Volumetric-flux conversions between in/min and cm/hr 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.

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).
