1. What is the Volume of 1 Gallon of Water?

Definition: One US gallon of water occupies exactly 231 cubic inches of volume at standard temperature and pressure.

Purpose: This standard measurement is used in engineering, plumbing, and various scientific calculations involving fluid volumes.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = 231\ \text{in}³ \times G \]

Where:

\( V \) — Volume in cubic inches
\( G \) — Number of gallons
231 — Cubic inches per gallon (constant)

Explanation: The calculator multiplies the number of gallons by 231 to convert to cubic inches.

3. Importance of Gallon Volume Calculation

Details: Knowing this conversion is essential for tank design, pipe sizing, hydraulic calculations, and any application requiring precise volume measurements.

4. Using the Calculator

Tips: Simply enter the number of gallons you want to convert to cubic inches. The default shows 1 gallon = 231 in³.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1 gallon exactly 231 cubic inches?
A: This was established by British law in 1824 and adopted by the US as the standard wine gallon measurement.

Q2: Does this apply to all liquids or just water?
A: This is the volume measurement for any liquid - the actual weight varies by density.

Q3: How does temperature affect this measurement?
A: The volume changes slightly with temperature, but 231 in³ remains the standard reference at 60°F.

Q4: What about imperial gallons?
A: Imperial gallons (UK) are different - 1 imperial gallon = 277.42 cubic inches.

Q5: How many cubic feet is 1 gallon?
A: 1 gallon = 231 in³ = 0.13368 cubic feet (231 ÷ 1728).
