1. What is a Tank Volume Calculator?

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

Purpose: It helps determine tank capacity for water storage, fuel tanks, aquariums, and other liquid containers.

2. How Does the Calculator Work?

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:

\( V_{gal} \) — Volume in gallons
\( L, W, H \) — Length, Width, Height in inches (rectangular)
\( r, h \) — Radius and Height in inches (cylindrical)
231 — Cubic inches per gallon conversion factor

3. Importance of Tank Volume Calculation

Details: Accurate volume calculations ensure proper system design, dosing accuracy, and compliance with regulations.

4. Using the Calculator

Tips:

Select tank shape (rectangular or cylindrical)
Enter dimensions in inches
All values must be > 0
For cylindrical tanks, measure radius (half of diameter)

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: There are 231 cubic inches in one US gallon (standard conversion).

Q2: Can I use this for metric measurements?
A: No, this calculator is for inches/gallons. For liters, use different conversion factors.

Q3: Does this account for tank thickness?
A: No, this calculates internal volume. For external dimensions, subtract wall thickness.

Q4: How accurate is this calculation?
A: It's mathematically precise but doesn't account for internal fixtures or irregular shapes.

Q5: What about oval or other shaped tanks?
A: This calculator handles only rectangular and cylindrical shapes. Other shapes require different formulas.
