Understand The CFM to GPH Conversion Process
For example, a water fountain in a park. The pump pushes air at 3 CFM to create those beautiful water patterns. But what if you wanted to know how much water flows in Gallons per Hour (GPH) instead? Let’s find out.
Conversion Steps
Conversion Formula
The basic rule is:
1 CFM = 448.8312 GPH
(one cubic foot of air moving per minute is equal to 448.8312 gallons of water per hour.)
so, to find GPH, multiply CFM by 448.8312:
Now, we will Plug in the Numbers
Our fountain system moves 3 CFM, we multiply:
It means 3 CFM is equal to about 1,346.49 GPH.
