Basic units of water measurement
There are two basic units of water measurement from a water management perspective. For water that is in motion, cubic feet per second (cfs) is the unit of measure. For water that is stored or impounded, the acre-foot (af) is how water is measured.
Cubic feet per second (cfs):
* 1 cubic foot = 7.4805 gallons.
* 1 cubic foot per second = 7.4805 gallons flowing by a particular point in 1 second.
* 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water.
* 1 cfs is equivalent to 448.8 gallons of water flowing per minute.
* 1 cfs will produce 724 acre-feet of water per year.
* 1 cfs = 38.4 miner’s inches of water.
Acre-foot (af):
* 1 acre = 43,560 square feet.
* 1 acre-foot = 43,560 cubic feet.
* 1 acre-foot = 325,851 gallons of water = 1233 cubic meters of water.
* 1 acre-foot = 0.504 cfs/ day.
Other conversions:
* 1 US gallon = 0.1337 cubic feet = 3.79 liters.
* 1 Million gallons = 3.07 acre-feet = 1.547 cfs per day.
* 1 gallon of water weighs 8.33 lbs.
* 1 cubic foot of water weighs 62.4 lbs.
* 1 part per million = 1 milligram per litre = 8.35 lbs per million gallons.
* 1 square mile = 640 acres.
* 1 million gallons per day = 694.4 gallons per minute.
