Conversion Formulas
Gallons are a nonSI measure of volume, with two different units  US Gallon and Imperial Gallon:
1 US Gallon = 128 US Fluid Ounces (fl oz) = 3.78541 liters → 1 liter = 0.26417 US Gallon
1 Imp Gallon = 160 Imp Fluid Ounces = 4.54609 liters → 1 liter = 0.219969 Imp Gallon
Also, a cubic foot is a nonSI measure of volume, derived from the foot, the unit of length.
1 foot = 0.3048 m = 3.048 dm (decimeter)
Hence, one cubic feet equals to:
1 Foot^{3} = (3.048 dm)^{3} = 28.316846592 dm^{3}= 28.316846592 liters → 1 liter = 0.035314666 Foot^{3}
Thus, in order to convert volume given in gallons into volume given in cubic feet and vice versa, use these formulas:
1 liter = 0.035314666 Foot^{3} = 0.26417 US Gallon = 0.219969 Imp Gallon
Foot^{3} = 7.480523 US Gallon = 6.228835 Imp Gallon
US Gallon = 0.1336805 Foot^{3}
Imp Gallon = 0.1605436 Foot^{3}
Gallons to Cubic Feet and Cubic Feet to Gallons Conversion Examples
If You have 4.7 gallons (US/Imp) that would be:
Volume_{(cubic feet)} = 4.7 * 0.1336805 = 0.62829835 Feet^{3}
Volume_{(cubic feet)} = 4.7 * 0.1605436 = 0.75455492 Feet^{3}
Similarly:
 1000 US Gallons = 133.6805 Feet^{3}
 500 Imp Gallons = 80.2718 Feet^{3}
 20 Feet^{3} = 149.61 US Gallons = 124.57 Imp Gallons
etc.
