What is CFM to LPM and Why Should You Care?

Have you ever heard of CFM? It stands for Cubic Feet per Minute, and it's crucial in measuring air flow volume in various applications like HVAC systems, air compressors, and even ventilation. Why should you care about converting CFM to LPM (Liters per Minute)? If you're an engineer or technician working internationally, or dealing with equipment that uses metric measurements, this conversion is essential. It's not just about numbers; it's about ensuring the efficiency and compatibility of your systems.

How to Calculate CFM to LPM

Converting CFM to LPM is straightforward once you know the conversion factor.

The Formula

[\text{LPM} = \text{CFM} \times 28.316847]

To convert in the opposite direction:

[\text{CFM} = \text{LPM} \div 28.316847]

Where:

  • CFM is the Cubic Feet per Minute
  • LPM is the Liters per Minute

Calculation Example

Suppose you have an air flow rate of 150 CFM. How do you convert that into LPM?

[\text{LPM} = 150 \times 28.316847 = 4247.53]

So, with 150 CFM, you get approximately 4247.53 LPM.

Conversion Table

Cubic Feet per Minute (CFM) Liters per Minute (LPM)
50 1415.84
100 2831.68
200 5663.37
500 14158.42

Converting between CFM and LPM is essential for ensuring your air flow systems work correctly across different measurement standards.
