Conversion Definitions
Gallon: A gallon is a unit of volume used in the United States and some other countries, mostly to measure liquids. One US gallon equals 231 cubic inches, or approximately 3.785 liters. It is commonly used for fuel, milk, and water measurements.
Cubic: Cubic refers to a measure of volume expressed in terms of the cube of a length unit, like cubic feet or cubic meters. It represents the space occupied by a cube with edges of a specified length. It quantify how much three-dimensional space an object or substance occupies.
Conversion FAQs
Can I convert gallons to cubic feet for any liquid?
The conversion between gallons and cubic feet applies to volume alone, so it is valid for any liquid or gas. However, it does not consider density or weight differences, so converting mass requires additional calculations.
Why is the conversion factor 0.133681?
This factor comes from the relationship between gallons and cubic inches, and cubic inches to cubic feet. Since one gallon equals 231 cubic inches, and one cubic foot equals 1728 cubic inches, dividing 231 by 1728 results in approximately 0.133681 cubic feet per gallon.
Can I use this conversion for UK gallons?
No, the UK gallon is larger than the US gallon. This conversion factor is only for US gallons. To convert UK gallons to cubic feet, a different conversion factor (about 0.160544) must be used.
Does temperature affect the volume conversion?
The volume conversion assumes standard temperature and pressure. Temperature changes can affect the volume of liquids and gases, causing slight variations. For precise work, temperature corrections may be necessary.
What is the easiest way to convert gallons to cubic feet without tools?
Multiplying the gallon value by 0.133681 gives a quick estimate of cubic feet. Using a calculator or conversion chart helps accuracy, but a rough mental estimate is possible by remembering roughly 1 gallon is about 0.13 cubic feet.
