This is granted that the water remain at constant temp., and at a point to have the stated volume.
If you remember the following facts, you'll never go wrong: ==> 1 cubic foot = 1,728 cubic inches ==> 231 cubic inches = 1 gallon
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.
3 (cubic feet) = 22.4415584 US gallons FYI: Google "convert 3 cubic feet to gallons"
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
100 gallons = 13.37 cubic feet.
For US gallons, use this conversion: US gallons x 0.134 = cubic feet.So, 31.5 x 0.134 = 4.221 cubic feet.
To convert gallons to cubic feet, you can use the conversion factor that 1 gallon is approximately 0.133681 cubic feet. Therefore, to convert 100 gallons to cubic feet, you multiply 100 by 0.133681, which equals about 13.3681 cubic feet.
Multiply by 7.481
Gallons are a measurement of volume; cubic feet is a measurement of area. You cannot convert between the two.
