One cubic foot per hour is exactly 0.0004719474432 cubic meters per minute, so converting cubic feet per hour to cubic meters 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.
Compressor and large-fan output in metric markets. Gas appliance and small-flow rating 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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in cubic meters per minute, so you can sanity-check whether your answer is a plausible size.
The formula
cubic feet per hour- The amount you are converting, in cubic feet per hour
0.0004719474432- The exact number of cubic meters per minute in one cubic foot per hour
cubic meters per minute- The converted result
How it works, step by step
- Enter the value in cubic feet per hour.
- It is multiplied by 0.0004719474432, the exact factor between the two units.
- The answer is shown in cubic meters per minute, with the reverse conversion beneath it.

Worked examples
A garden hose: 38.1 CFH in cubic meters per minute
At 38.1 CFH (a garden hose), the same quantity in cubic meters per minute is 38.1 × 0.000471947 = 0.0179812 m³/min. One cubic foot per hour is 0.000471947 cubic meters per minute, so the numbers shrink as expected.
A bathroom tap: 12.7 CFH in cubic meters per minute
Take a bathroom tap, roughly 12.7 CFH. The conversion is a single multiplication — 12.7 × 0.000471947 — giving 0.00599373 m³/min. Because the relationship is proportional, doubling the input doubles the answer to 0.0119875 m³/min.

Frequently asked questions
How many cubic meters per minute are in one cubic foot per hour?
Exactly 0.0004719474432. 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 hour to cubic meters per minute?
cubic meters per minute = cubic feet per hour × 0.0004719474432. Reversed, cubic feet per hour = cubic meters per minute ÷ 0.0004719474432, which is the same as multiplying by 2118.88000329.
Which is the bigger unit, the cubic foot per hour or the cubic meter per minute?
The cubic meter per minute. One cubic foot per hour is only 0.000471947 of a cubic meter per minute, so it takes 2118.88 cubic feet per hour to make one cubic meter 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 hour?
Gas appliance and small-flow rating in the US.
What is a cubic meter per minute?
Compressor and large-fan output in metric markets.
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 CFH to m³/min in my head?
Plenty of people do this in their head: divide by 2100 instead of using the exact factor 0.0004719474432. At 100 that shortcut gives 0.047619048 cubic meters per minute, off by 0.0004243 cubic meters per minute or about 0.90%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
