Quick and Easy
Conversion Table - Water Flow Rates and Volume
Conversions
The conversion table below is for water flow rates and water
volume equivalencies between CFS (cubic feet per second), GPM
(gallons per minute), AFA (acre-feet per annum) and MI (miner's
inches). The MI standard in this table is 40 MI per CFS (see
the discusison on variable definitions for MI standards on the
miner's inch
page). The table below is for reference only, and no
representations are made to its accuracy.
