Common Conversion Factors For Water and Wastewater

For water treatment or reservoirs, there are several conversion factors which are commonly used:

  • Since 1 day = 24 hours = 1440 minutes, therefore 15 minutes (1 day/1440 minutes) = 15/1440 ~= 0.010416667 ~= 0.01 days.
  • 1 million gallons per day (MGD) = 3.069 acre feet per day (ac-ft/day) = 1.55 cubic feet per second (cfs) = 694 gallons per minute (gpm)
  • 1 gallon = 3785 milliliters = 3.785 liters = 8.34 pounds of water.

Examples of conversions:

  1. 55 gallons of water (8.34 pound/1 gallon) = 458.7 pounds.
  2. a hose running 20 gpm for 1 day (1440 minutes/1 day) = 28,800 gallons/day.
  3. a one-ton truck can carry 2000 pounds (1 gallon/8.34 pounds) = 240 gallons (water).

    “Romance reading and writing might be seen ... as a collectively elaborated female ritual through which women explore the consequences of their common social condition as the appendages of men and attempt to imagine a more perfect state where all the needs they so intensely feel and accept as given would be adequately addressed.”
    —Janice A. Radway (b. 1949)

    “The conversion of a savage to Christianity is the conversion of Christianity to savagery.”
    —George Bernard Shaw (1856–1950)

    “The goal of every culture is to decay through over-civilization; the factors of decadence,—luxury, scepticism, weariness and superstition,—are constant. The civilization of one epoch becomes the manure of the next.”
    —Cyril Connolly (1903–1974)

    “This sand seemed to us the connecting link between land and water. It was a kind of water on which you could walk, and you could see the ripple-marks on its surface, produced by the winds, precisely like those at the bottom of a brook or lake. We had read that Mussulmans are permitted by the Koran to perform their ablutions in sand when they cannot get water, a necessary indulgence in Arabia, and we now understand the propriety of this provision.”
    —Henry David Thoreau (1817–1862)
