Conversion Definitions
Gallons: A gallon is a unit of volume measurement, commonly used in the United States and some other countries for liquids like water, fuel, and milk. The US liquid gallon equals 128 fluid ounces or about 3.785 liters. Gallons measure capacity mostly in everyday liquid quantities.
Cubic: Cubic refers to a measurement of volume expressed as a cube of length units, such as cubic feet, cubic meters, or cubic inches. It represents the space occupied by an object or substance within three dimensions: length, width, and height multiplied together to give volume.
Conversion FAQs
Can I convert gallons to cubic inches using the same method?
Yes, but the conversion factor differs. One gallon equals 231 cubic inches, so multiply gallons by 231 to get cubic inches. The formula changes depending on the cubic unit you want to convert to.
Does temperature affect the gallons to cubic feet conversion?
The conversion between gallons and cubic feet is a fixed ratio based on volume units, so temperature doesn’t affect it. However, liquids can expand or contract with temperature, affecting volume physically but not the mathematical conversion.
Why is the conversion factor 0.133681 for gallons to cubic feet?
Because one US gallon is defined as exactly 231 cubic inches, and one cubic foot is 1728 cubic inches, dividing 231 by 1728 gives approximately 0.133681 cubic feet per gallon. This ratio is constant for volume conversions.
Is this conversion valid for UK gallons as well?
No, the UK (Imperial) gallon is different, about 4.546 liters compared to 3.785 liters for US gallon. To convert UK gallons to cubic feet, a different factor must be used, about 0.160544 cubic feet per UK gallon.
How accurate is this conversion for practical use?
The conversion factor 0.133681 is accurate for most practical purposes including engineering, cooking, and liquid storage. Minor rounding differences might occur but generally, it’s precise enough for everyday needs.
