Formula for converting Gallons to Cubic Feet
Converting from gallons to cubic feet is relatively straightforward, but depends on the measurement system you're using. For US measurements, the formula is: 1 gallon x .133681 ft³ while for UK measurements, the formula is: 1 gallon x .160544 ft³. For the metric system, there is no "gallon" conversion because metric doesn't use gallons. However, you can first convert gallons to liters and then to cubic feet.
For example, let's imagine you need to convert 4.23 gallons to cubic feet (ft³):
US formula: 4.23 x .133681 = .5655 ft³
UK formula: 4.23 x .160544 = .6791 ft³
US Gallon to Metric: 4.23 x 3.78541 (liters) x .0353147 (liters to cubic feet) = .5655 ft³
UK Gallon to Metric: 4.23 x 4.54609 (liters) x .0353147 (liters to cubic feet) = .6791 ft³
