Gallons in a Tank Calculator

Tank Volume Formulas:

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

Tank Shape:

Length:

inches

Width:

Height:

inches

Tank Volume (gallons):

Definition: This calculator determines the volume of liquid a tank can hold in gallons based on its dimensions.

Purpose: It helps in sizing tanks for storage, determining capacity for industrial processes, or calculating volumes for aquariums and pools.

The calculator uses different formulas based on tank shape:

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

Where:

Explanation: The calculator first computes cubic inches, then converts to gallons by dividing by 231.

Details: Accurate volume calculations ensure proper system design, prevent overfilling, and help with dosing chemicals or treatments.

Tips: Select tank shape, enter dimensions in inches. For cylindrical tanks, measure diameter and divide by 2 for radius.

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

Q2: How do I measure tank dimensions?
A: Measure inside dimensions for accurate capacity. For height, measure from bottom to fill line.

Q3: Can I calculate for oval or other shapes?
A: This calculator handles basic shapes. Complex shapes require more advanced calculations.

Q4: Does this account for tank contents?
A: No, this calculates total volume. Actual usable volume may be less depending on equipment.

Q5: How accurate is this calculation?
A: It's mathematically precise for perfect geometric shapes. Real tanks may vary slightly.
