Conversion Definitions
Gallons: A gallon is a unit of volume measurement used primarily in the United States, equal to 128 fluid ounces. It measures the amount of liquid contained within a container. Gallons can be US liquid or dry gallons; here, the liquid gallon is used, which equals approximately 3.785 liters.
Cubic: Cubic refers to the volume measurement based on cubic units, such as cubic feet or cubic meters. It describes the space occupied by a three-dimensional object or substance, calculated by multiplying length × width × height, resulting in units like cubic feet or cubic inches.
Conversion FAQs
Can gallons be converted directly to cubic feet for any liquid?
Gallons measure volume of liquids, and cubic feet measure volume too, so direct conversion applies regardless of liquid type. The conversion factor between gallons and cubic feet remains constant because both units measure volume, not mass or density.
Why is the conversion factor 0.133681 when converting gallons to cubic feet?
The factor 0.133681 comes from dividing the volume of one gallon in cubic inches (231 cu in) by the volume of one cubic foot in cubic inches (1728 cu in). This ratio converts gallons to cubic feet without changing the actual volume.
Is it possible to convert gallons to cubic meters instead?
Yes, gallons can be converted to cubic meters by using a different factor. Since 1 gallon equals approximately 0.00378541 cubic meters, multiply the gallon value by this factor to get cubic meters.
Does temperature or pressure affect gallons to cubic feet conversion?
The conversion only relates to volume units, so temperature or pressure does not affect the mathematical factor. However, physical volume of liquids might change with conditions, but the units themselves don’t change their relation.
How accurate are conversions when rounding off gallons to cubic feet?
Conversions are accurate to the degree of decimal places used. Rounding to four decimal places like 0.1337 for the factor introduces minor differences, but for most practical purposes it’s precise enough.
