Volumetric Flux

in/mintocm/s

Convert inches per minute (volumetric flux) (in/min) to centimetres per second (volumetric flux) (cm/s).

Factor1 in/min = 0.04233333 cm/s

Converter

in/min

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

Result
0.0423333cm/s

Formula

Formula
cm/s = in/min × 0.04233333

Multiply any value in inches per minute (volumetric flux) by 0.04233333 to obtain the value in centimetres per second (volumetric flux).

Worked example

Convert 1 in/min to cm/s.

  1. 01Start with 1 in/min.
  2. 02Multiply by the conversion factor: 1 × 0.04233333 = 0.0423333 cm/s.
Result1 in/min = 0.0423333 cm/s

FAQ

What is the conversion factor from in/min to cm/s?
1 in/min equals 0.04233333 cm/s. To convert, multiply the value in inches per minute (volumetric flux) by 0.04233333.
How do I convert 1 in/min to cm/s?
1 in/min = 0.0423333 cm/s. For any value, multiply by 0.04233333.
How do I convert cm/s back to in/min?
Divide by the same factor — or equivalently, multiply by 23.62205. So 1 cm/s = 23.622 in/min.
When would I need to convert inch per minute (volumetric flux) to centimetre per second (volumetric flux)?
Volumetric-flux conversions between in/min and cm/s 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).
