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

understand this, experiment using 1 AFA. The results will match
