Looking at using a swamp cooler pump to return water from filter to tank. I have done this before but don't remember how to change CFM to GPH.

How would I figure out GPH whith a pump marked in CFM?
 
Thank you but this doesn't seem right a 10,000CFM pump for a swamp cooler is producing 4,483,018.868 US GPH. This cant be right? that is like turning my aquarium water over 90,000 times an hour and I have a hard time seeing a small pump producing over 4milion gallons an hour through a little hose.

Am I using this calculator wrong?
 
wait, wait - i'm guessing that CFM is, what, cubic feet per minute?
so does it make sense that the pump is pumping 10,000 CFM?
maybe it is pumping 10.0 CFM, therefore giving you 4,483 GPH?
That still seems high. what's a swamp cooler pump?
