How it works
We use m^3/h = cfm x 1.69901079552.
Exact relationship: 1 cfm = 1.69901079552 m^3/h.
Example: 100 cfm = 169.901 m^3/h.
Notes: Results are rounded in the default view.
Examples
- 100 cfm = 169.901 m^3/h
- 1000 cfm = 1699.011 m^3/h
- 10000 cfm = 16990.108 m^3/h
FAQ
What physical quantity do cubic feet per minute and cubic meters per hour express?
Cubic feet per minute express airflow and bulk volumetric movement at a building or equipment scale. Cubic meters per hour express larger metric flow rates and are common in building, utility, and industrial process systems.
What is the difference between cubic feet per minute and cubic meters per hour?
Cubic feet per minute and cubic meters per hour both express volumetric flow rate, but they are favored in different liquid, air, utility, and process-system contexts.
What is the history of the cubic foot per minute?
Cubic feet per minute became standard in HVAC, fans, blowers, and air-system practice where foot-based volume units were already common.
What is the history of the cubic meter per hour?
Cubic meters per hour follow from SI volume conventions and became common in international HVAC, water, and process engineering.
Were the cubic foot per minute and cubic meter per hour discovered by a specific person?
Cubic feet per minute are a conventional flow unit rather than a one-person discovery. Cubic meters per hour are a derived engineering unit rather than a single-person discovery.
Where are cubic feet per minute and cubic meters per hour used in science and engineering?
Cfm is used in HVAC, compressed air, ventilation, dust collection, fans, and equipment airflow specs. Cubic meters per hour are used in HVAC, water treatment, ventilation, bulk process systems, and utility planning.
Why do flow-rate units matter in calculations?
Flow-rate units affect pump sizing, piping, ventilation, residence time, equipment selection, and process throughput. Keeping the unit attached helps avoid confusing static volume with volume per unit time.
Can I trust this for critical flow calculations?
Use this for convenience and verify against your governing standard, equipment curve, or controlled engineering source for critical work. Real systems still depend on pressure, temperature, losses, and operating conditions.
