Frequently Asked Questions
How do I convert LPM to CFM?
Divide LPM by 28.3168. For quick estimates, multiply LPM by 0.0353 to get CFM.
What is the difference between LPM and SLPM?
LPM is the actual flow rate in liters per minute at site conditions. SLPM (Standard LPM) normalizes to standard temperature and pressure, similar to the SCFM/ACFM distinction.
Can I use this for liquid flow too?
The unit conversion is the same (1 ft³ = 28.317 L), but liquid flow in CFM is rare. GPM is the standard for liquids. This converter is intended for gas flow.
