This is granted that the water remain at constant temp., and at a point to have the stated volume.
Cubic feet x 7.481 = gallons
Gallons x 0.133681 = cubic feet
To convert gallons to cubic feet, multiply by 0.1337. So, 12481 gallons of water is approximately 1668 cubic feet.
There are approximately 22.5 gallons in 3 cubic feet of water.
1 US gallon = 0.133680556 Cubic Feet (ft3); and 1 day = 24 hours = 1,440 Minutes. Math equation for conversion where "x=number of gallons per day" is: (x / 1440) x 0.133680556 Example: If x=30 (gallons per day), then: 0.208333 x 0.133680556 = 2.785 ft3 per Minute.
Let's calculate cubic feet first, then convert to gallons. Volume=pir2h=3.14159x0.252x3=0.59 cubic feet 0.59 cubic feetx7.48 gallons/cubic foot=4.4 gallons
a cubic foot=7.4805195 gallons
For US gallons, use this conversion: US gallons x 0.134 = cubic feet.So, 31.5 x 0.134 = 4.221 cubic feet.
There are 7.48 gallons in 1 cubic foot, so 100 gallons of water would equal approximately 13.36 cubic feet.
Multiply by 7.481
Cubic feet per hour x 7.48 = gallons per hour
Gallons are a measurement of volume; cubic feet is a measurement of area. You cannot convert between the two.
There are approximately 7.48 gallons in 1 cubic foot. To convert 2000 gallons to cubic yards: 2000 gallons / 7.48 gallons per cubic foot = 267.38 cubic feet. Then, to convert cubic feet to cubic yards: 267.38 cubic feet / 27 cubic feet per cubic yard = 9.91 cubic yards.
