Definition: This calculator estimates the volume of liquid in gallons based on container dimensions in inches.

Purpose: It helps determine how much liquid a container can hold, useful for industrial, chemical, or household applications.

The calculator uses these formulas:

\[ V_{gal} = \frac{L \times W \times H}{231} \] (rectangular)
\[ V_{gal} = \frac{\pi \times r^2 \times h}{231} \] (cylindrical)

Where:

Explanation: The formulas convert cubic inches to gallons (1 gallon = 231 cubic inches).

Details: Accurate volume calculations ensure proper container sizing, chemical mixing ratios, and storage capacity planning.

Tips: Select container shape, enter dimensions in inches, and click Calculate. All dimension values must be > 0.

Q1: Why 231 cubic inches per gallon?
A: This is the standard US gallon volume defined as 231 cubic inches.

Q2: Can I calculate metric volumes?
A: This calculator uses US customary units. For liters, use different conversion factors.

Q3: Does this account for container thickness?
A: No, use internal dimensions for accurate results.

Q4: How accurate are these calculations?
A: They're theoretical volumes. Actual capacity may vary with container shape irregularities.

Q5: What about tapered or irregular containers?
A: This calculator handles only regular rectangular and cylindrical shapes.
