How it works
We use cfm = L/s x 2.11888000329.
Exact relationship: 1 L/s = 2.11888000329 cfm.
Example: 1 L/s = 2.119 cfm.
Notes: Results are rounded in the default view.
Examples
- 1 L/s = 2.119 cfm
- 10 L/s = 21.189 cfm
- 100 L/s = 211.888 cfm
FAQ
What physical quantity do liters per second and cubic feet per minute express?
Liters per second express higher-rate metric flow more compactly than liters per minute for some engineering applications. Cubic feet per minute express airflow and bulk volumetric movement at a building or equipment scale.
What is the difference between liters per second and cubic feet per minute?
Liters per second 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 second?
Liters per second became common where SI-based flow reporting benefits from second-based rate calculations.
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 second and cubic foot per minute discovered by a specific person?
Liters per second are a standardized derived flow unit rather than something discovered by one person. Cubic feet per minute are a conventional flow unit rather than a one-person discovery.
Where are liters per second and cubic feet per minute used in science and engineering?
Liters per second are used in piping, civil utilities, process design, fire flow, and engineering calculations. 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.
