This is granted that the water remain at constant temp., and at a point to have the stated volume.
To convert cubic inches to gallons, divide by 231. To convert gallons to cubic feet, divide by 7.48. To convert cubic feet to gallons, multiply by 7.48.
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.
a cubic foot=7.4805195 gallons
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
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.
