How it works
We use cfm = L/min x 0.0353146667215.
Exact relationship: 1 L/min = 0.0353146667215 cfm.
Example: 10 L/min = 0.353 cfm.
Notes: Results are rounded in the default view.
Examples
- 10 L/min = 0.353 cfm
- 100 L/min = 3.531 cfm
- 1000 L/min = 35.315 cfm
FAQ
What physical quantity do liters per minute and cubic feet per minute express?
Liters per minute express moderate metric flow rates and are common where liters are the preferred base volume unit. Cubic feet per minute express airflow and bulk volumetric movement at a building or equipment scale.
What is the difference between liters per minute and cubic feet per minute?
Liters per minute and cubic feet per minute both express volumetric flow rate, but they are favored in different liquid, air, utility, and process-system contexts.
What is the history of the liter per minute?
Liters per minute follow naturally from metric volume practice and are common in labs, medical devices, and process systems.
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.
Were the liter per minute and cubic foot per minute discovered by a specific person?
Liters per minute are a standardized derived flow unit rather than a discovery by one person. Cubic feet per minute are a conventional flow unit rather than a one-person discovery.
Where are liters per minute and cubic feet per minute used in science and engineering?
Liters per minute are used in pumps, oxygen systems, coolant circuits, process lines, and lab equipment. Cfm is used in HVAC, compressed air, ventilation, dust collection, fans, and equipment airflow specs.
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.
