Enter the total cubic feet per second (CFS) into the GPM from CFS Calculator. The calculator will evaluate the GPM from CFS. 

GPM from CFS Formula

The following two example problems outline the steps and information needed to calculate the GPM from CFS.

GPM = CFS * 7.481 * 60

Variables:

  • GPM is the GPM from CFS (gallons per minute)
  • CFS is the total cubic feet per second (CFS) 

How to Calculate GPM from CFS?

The following steps outline how to calculate the GPM from CFS.


  1. First, determine the total cubic feet per second (CFS). 
  2. Next, gather the formula from above = GPM = CFS * 7.481 * 60.
  3. Finally, calculate the GPM from CFS.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total cubic feet per second (CFS) = 30

GPM = CFS * 7.481 * 60 = ?
