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.
