L/min to CFM conversion

[Jeff7]

What's the formula to convert between Liters/min and CFM?

 

[ThisIsMatt]

1 liter = 0.0353 ft^3

According to this page,

1 CFM = 28.328 L/min
1 L/min = 28.329 CFM

 

[Jeff7]

Wait, aren't those last 2 equations contradictory, or am I just in a really stupid state right now?
Basically, I have a blower here that moves 12L/min of air; I need a comparable CFM rating. Geez, some companies rate in L/min, some cubic meters per minute, and then CFM. Sheesh!!!

Yes, those numbers seemed kind of funky. According to this site:

1 Liter = 0.03531 Cu. Ft.
1 Cu. Ft. = 28.32 Liters

I'm inclined to believe this information more.

Ok, so ThisIsMatt spoke the truth. I came back to this thread with 2 replies, 1 of which gave conflicting info.
Thanks all.

Calculate it yourself:

1ft³ = 12³ in³ = 1728 cubic inches
1 cubic inch = 16.387064 cm³

1728 * 16.387064 = 28316.846592 cubic centimeters in one cubic foot

1 L = 1000 cm³, so divide that by 1,000:

28.32 liters/min = 1 cfm

Or conversely:

1 liter/min = 0.035 cfm

So yes, that is correct.
