Tank Volume Formulas:
Rectangular: \[ V_{gal} = \frac{L \times W \times H}{231} \]
Cylindrical: \[ V_{gal} = \frac{\pi \times r^2 \times h}{231} \]

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 storage, industrial applications, or aquarium setups.
The calculator uses different formulas depending on tank shape:
Rectangular: \[ V_{gal} = \frac{L \times W \times H}{231} \]
Cylindrical: \[ V_{gal} = \frac{\pi \times r^2 \times h}{231} \]
Where:
Note: 231 cubic inches equals 1 US gallon.
Details: Accurate volume calculation ensures proper sizing for storage needs, chemical dosing, and system design.
Tips: Select tank shape, enter dimensions in inches, and click Calculate. All values must be > 0.
Q1: Why divide by 231?
A: Because 231 cubic inches equals 1 US gallon, the standard conversion factor.
Q2: Can I use centimeters instead of inches?
A: No, this calculator requires inches since the conversion factor (231) is based on cubic inches.
Q3: How accurate is this calculation?
A: It provides theoretical maximum volume. Actual capacity may differ due to tank shape variations.
Q4: Does this work for oval or irregular tanks?
A: No, this calculator is for standard rectangular or cylindrical tanks only.
Q5: What about tank thickness?
A: This calculates internal volume. For external dimensions, subtract wall thickness from measurements.
