One cubic foot per minute is exactly 28,316.84659 milliliters per minute, so converting cubic feet per minute to milliliters per minute is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
The airflow rating for fans, HVAC and compressors in the US. Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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 milliliters per minute, which is usually more useful than the bare number.
The formula
cubic feet per minute- The amount you are converting, in cubic feet per minute
28,316.846592- The exact number of milliliters per minute in one cubic foot per minute
milliliters per minute- The converted result
How it works, step by step
- Enter the value in cubic feet per minute.
- It is multiplied by 28,316.846592, the exact factor between the two units.
- The answer is shown in milliliters 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: 0.212 CFM in milliliters per minute
A bathroom tap comes to about 0.212 CFM. Multiplying by the factor: 0.212 × 28,316.8 = 6003.17 mL/min. Dividing the answer back by 28,316.8 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A dripping tap: 0.000212 CFM in milliliters per minute
Take a dripping tap, roughly 0.000212 CFM. The conversion is a single multiplication — 0.000212 × 28,316.8 — giving 6.00317 mL/min. Because the relationship is proportional, doubling the input doubles the answer to 12.0063 mL/min.

Frequently asked questions
How many milliliters per minute are in one cubic foot per minute?
Exactly 28,316.846592. 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 cubic feet per minute to milliliters per minute?
milliliters per minute = cubic feet per minute × 28,316.846592. Reversed, cubic feet per minute = milliliters per minute ÷ 28,316.846592, which is the same as multiplying by 3.53146667215e-05.
Which is the bigger unit, the cubic foot per minute or the milliliter per minute?
The cubic foot per minute. One cubic foot per minute equals 28,316.8 milliliters 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 cubic foot per minute?
The airflow rating for fans, HVAC and compressors in the US.
What is a milliliter per minute?
Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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 CFM to mL/min in my head?
Plenty of people do this in their head: multiply by 28,000 instead of using the exact factor 28,316.84659. At 100 that shortcut gives 2,800,000 milliliters per minute, off by 31684.659200 milliliters per minute or about 1.12%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
