What is CFM and M³/min?

CFM (Cubic Feet per Minute)

is a common airflow measurement in the United States and other imperial system regions. It indicates how many cubic feet of air pass a point each minute.

Understanding how to convert between them is critical in:

Air compressor sizing

Cross-border equipment comparison

Technical evaluations and quotations

M³/min (Cubic Meters per Minute)

is the metric equivalent, commonly used in Europe, Asia, and international engineering standards.

How to Choose the Right Air Compressor Air Flow (CFM or m³/min)?

Choosing the correct compressor size starts with understanding your equipment’s maximum air consumption. Confirm the required CFM (or m³/min) with your equipment supplier under full load conditions.

Then, apply a basic sizing rule:

Required Airflow = Maximum Consumption × 1.15

This 1.15 factor accounts for pipe losses, valve leakage, and system inefficiencies.

Example:

If your machine’s maximum demand is 200 CFM, you should select a compressor rated at at least 230 CFM. Then choose your compressor type—screw, scroll, piston, or centrifugal—based on your usage scenario.

✅ Tip: Never select a compressor with capacity exactly equal to your demand. Always reserve at least 15% buffer.

Frequently Asked Questions

Is CFM the same as SCFM?

No. SCFM accounts for standardized temperature and pressure. CFM may vary by conditions.

Can I use this conversion for high-pressure air?

Not directly. These formulas assume atmospheric pressure. For high-pressure systems, refer to SCFM or ACFM.

How accurate is the conversion?

Using the standard multiplier, it’s accurate for most industrial applications.

What is the difference between CFM and m³/min?

CFM is an imperial unit used in the U.S., while m³/min is a metric unit commonly used in international engineering and manufacturing.

Why is CFM conversion important for compressor selection?

Different brands and regions use different units. Correct conversion ensures accurate equipment sizing and avoids over- or under-specification.
