Conversion Definitions
Gallons: Gallons is a unit of volume commonly used in the United States for measuring liquids. One US liquid gallon equals 128 fluid ounces or about 3.785 liters. It is used in many applications, including fuel, water, and other liquid measurements, especially in everyday life and business.
Cubic: Cubic refers to volume measurements based on cubes, such as cubic feet, cubic meters, or cubic inches. It represents the amount of three-dimensional space an object or substance occupies. Cubic units are calculated by multiplying length, width, and height measurements in the same units.
Conversion FAQs
Why is the conversion factor 0.13368 used for gallons to cubic feet?
This factor comes from the definition of one US liquid gallon, which is exactly 231 cubic inches. Since one cubic foot contains 1728 cubic inches (12×12×12), dividing 231 by 1728 gives approximately 0.13368 cubic feet per gallon.
Can I use the same conversion factor for UK gallons?
No, the UK (imperial) gallon is larger than the US gallon, about 1.20095 times bigger. So it uses a different conversion factor to cubic feet. The 0.13368 value applies only to US liquid gallons.
How precise is this conversion for practical uses?
The conversion factor is exact based on defined units. However, rounding during calculations may cause small differences. For everyday use, rounding to 4 decimal places is precise enough for volume measurements.
Is it possible to convert gallons directly to cubic meters?
Yes, but the factor is different. One US gallon equals approximately 0.003785 cubic meters. The conversion requires multiplying gallons by 0.003785 instead of 0.13368.
What common mistakes happen when converting gallons to cubic feet?
Using incorrect gallon types (US vs UK), mixing volume units without conversion, or forgetting to multiply by the conversion factor causes errors. Also, confusing cubic feet with cubic inches or meters leads to wrong results.
