To convert milliliters per minute to cubic feet per minute, multiply by 3.531466672e-05. That factor is the whole relationship: both units measure volumetric flow, so the conversion is a proportion with no offset and no substance-specific constant.
Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min. The airflow rating for fans, HVAC and compressors in the US.
Standard versus actual volume. Gas flow in CFM depends on pressure and temperature, which is why compressor ratings say SCFM and specify the reference conditions. Converting the number is exact; comparing two ratings measured at different conditions is not. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into cubic feet per minute, which is usually more useful than the bare number.
The formula
milliliters per minute- The amount you are converting, in milliliters per minute
3.53146667215e-05- The exact number of cubic feet per minute in one milliliter per minute
cubic feet per minute- The converted result
How it works, step by step
- Enter the value in milliliters per minute.
- It is multiplied by 3.53146667215e-05, the exact factor between the two units.
- The answer is shown in cubic feet per minute, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A bathroom tap: 6000 mL/min in cubic feet per minute
Take a bathroom tap, roughly 6000 mL/min. The conversion is a single multiplication — 6000 × 3.53147e-05 — giving 0.211888 CFM. Because the relationship is proportional, doubling the input doubles the answer to 0.423776 CFM.
A garden hose: 1.8e+04 mL/min in cubic feet per minute
Take a garden hose, roughly 1.8e+04 mL/min. The conversion is a single multiplication — 1.8e+04 × 3.53147e-05 — giving 0.635664 CFM. Because the relationship is proportional, doubling the input doubles the answer to 1.27133 CFM.

Frequently asked questions
How many cubic feet per minute are in one milliliter per minute?
Exactly 3.53146667215e-05. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert milliliters per minute to cubic feet per minute?
cubic feet per minute = milliliters per minute × 3.53146667215e-05. Reversed, milliliters per minute = cubic feet per minute ÷ 3.53146667215e-05, which is the same as multiplying by 28,316.846592.
Which is the bigger unit, the milliliter per minute or the cubic foot per minute?
The cubic foot per minute. One milliliter per minute is only 3.53147e-05 of a cubic foot per minute, so it takes 28,316.8 milliliters per minute to make one cubic foot per minute.
What does this quantity actually measure?
Both units measure volumetric flow. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a milliliter per minute?
Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
What is a cubic foot per minute?
The airflow rating for fans, HVAC and compressors in the US.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
Is there a quick way to do mL/min to CFM in my head?
Plenty of people do this in their head: divide by 28,000 instead of using the exact factor 0.000035. At 100 that shortcut gives 0.0035714286 cubic feet per minute, off by 0.000040 cubic feet per minute or about 1.13%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
