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 yard is a nonSI measure of volume, derived from the yard, the unit of length.
1 Yard = 0.9144 m
Hence, one cubic yard equals to:
1 Yard^{3} = (0.9144 m)^{3} = 0.764554857984 m^{3} = 764.554 liters → 1 liter = 0.0013079506 Yard^{3}
Thus, in order to convert volume given in gallons into volume given in cubic yards and vice versa, use these formulas:
1 liter = 0.0013079506 Yard^{3} = 0.26417 US Gallon = 0.219969 Imp Gallon
Yard^{3} = 201.97 US Gallon = 168.18 Imp Gallon
US Gallon = 0.00495113 Yard^{3}
Imp Gallon = 0.00594606 Yard^{3}
Gallons to Cubic Yards and Cubic Yards to Gallons Conversion Examples
If You have 4.7 gallons (US/Imp) that would be:
US Gallons: Volume_{(cubic yards)} = 4.7 * 0.00495113 = 0.02327 Yards^{3}
Imp Gallons: Volume_{(cubic yards)} = 4.7 * 0.00594606 = 0.02794 Yards^{3}
Similarly:
 1000 US Gallons = 4.95113 Yards^{3}
 500 Imp Gallons = 2.97303 Yards^{3}
 20 Yards^{3} = 4039.48 US Gallons = 3363.57 Imp Gallons
etc.
