Conversion Formula:
| From: | To: |
The L Min To Cfm conversion calculates cubic feet per minute (CFM) from liters per minute (L/min). This conversion is essential in various engineering and HVAC applications where airflow measurements need to be converted between metric and imperial units.
The calculator uses the conversion formula:
Where:
Explanation: Since 1 cubic foot equals 28.3168 liters, dividing liters per minute by this conversion factor gives the equivalent flow rate in cubic feet per minute.
Details: Accurate flow rate conversion is crucial for HVAC system design, industrial ventilation, fan selection, and various engineering applications where consistent unit measurements are required across different standards and regions.
Tips: Enter the flow rate in liters per minute (L/min). The value must be a positive number. The calculator will automatically compute the equivalent value in cubic feet per minute (CFM).
Q1: Why is the conversion factor 28.3168?
A: This value comes from the fact that 1 cubic foot equals exactly 28.316846592 liters, which is typically rounded to 28.3168 for practical calculations.
Q2: What are common applications for this conversion?
A: HVAC system design, fan and blower specifications, industrial ventilation, air compressor ratings, and any application where airflow measurements need conversion between metric and imperial units.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between liters and cubic feet. The precision depends on the accuracy of your input measurement.
Q4: Can I convert CFM back to L/min?
A: Yes, to convert from CFM to L/min, multiply the CFM value by 28.3168.
Q5: Are there different conversion factors for different conditions?
A: The conversion factor remains constant as it's based on volume conversion. However, for gas flow measurements, temperature and pressure corrections might be needed for accurate mass flow calculations.
