Convert CFM to m³/min or m³/min to CFM by entering a flow value and get the equivalent air flow in the chosen unit using the 0.0283168 factor.
Quick Overview: CFM to m³/min
Both CFM and m³/min measure volumetric flow rate. The difference is only the volume unit used: cubic feet versus cubic meters.
Using 1 ft³ = 0.0283168 m³, you can convert between these airflow units with a single constant.
- 10 CFM = 0.283 m³/min
- 50 CFM = 1.416 m³/min
- 100 CFM = 2.832 m³/min
- 500 CFM = 14.158 m³/min
This conversion is commonly used in HVAC, ventilation, fan ratings, and engineering specifications where airflow may be expressed in either imperial or SI units.

CFM to m³/min Formula
The following formulas are used to convert between cubic feet per minute (CFM) and cubic meters per minute (m³/min).
m^3/min = CFM \times 0.0283168
CFM = \frac{m^3/min}{0.0283168}Variables:
- CFM is the airflow in cubic feet per minute
- m³/min is the airflow in cubic meters per minute
- 0.0283168 is the number of cubic meters in one cubic foot
To convert CFM to m³/min, multiply the airflow by 0.0283168. To convert m³/min back to CFM, divide the airflow by 0.0283168.
What is CFM to m³/min?
CFM and m³/min are both units of volumetric flow rate, which describes how much air or gas moves through a system in one minute. CFM is commonly used in the United States and in many HVAC and fan specifications, while m³/min is the SI-based equivalent used more often in scientific and international engineering applications. Converting between them allows airflow ratings to be compared across different unit systems.
How to Convert CFM to m³/min?
The following steps outline how to convert CFM to m³/min.
- First, determine the airflow in cubic feet per minute (CFM).
- Next, use the conversion constant 0.0283168 cubic meters per cubic foot.
- Multiply the CFM value by 0.0283168 to calculate the airflow in m³/min.
- If converting in reverse, divide the m³/min value by 0.0283168 to find CFM.
- After calculating, verify your answer with the calculator above.
Example Problem:
Use the following values as an example problem to test your knowledge.
Flow (CFM) = 100
Flow (m³/min) = 100 × 0.0283168 = 2.83168
CFM to m³/min Conversion Table
The table below lists several common CFM values converted to m³/min using the relationship m³/min = CFM × 0.0283168.
| Flow (CFM) | Multiply By | Flow (m³/min) |
|---|---|---|
| 10 | 0.0283168 | 0.283 |
| 25 | 0.0283168 | 0.708 |
| 50 | 0.0283168 | 1.416 |
| 75 | 0.0283168 | 2.124 |
| 100 | 0.0283168 | 2.832 |
| 250 | 0.0283168 | 7.079 |
| 500 | 0.0283168 | 14.158 |
In practical applications, airflow may be listed in either CFM or m³/min depending on the region, code standard, or manufacturer. Knowing the fixed conversion between cubic feet and cubic meters makes it easy to translate airflow ratings for ventilation systems, fans, blowers, and other fluid-moving equipment.
