How to use the calculator.
(1) Enter the number of AFA you wish to convert in the top of the
form. DO NOT USE COMMAS. (2) Select gpm, CFS, or CFM. (3) Click
"Calculate. The converted expression will appear in the last box
(conversion). If you selected CFS, the converted figure is an
expression in CFS. To recalculate with a different expression (for
example, gpm instead of CFS), be sure to select gpm, and click the
calculate button again so that the math will reset. If you don't
understand this, experiment using 1 AFA. The results will match the
formula above.
