Rectangular Tank Volume Formula:
From: | To: |
The rectangular tank volume calculation determines the capacity of a rectangular container in gallons using the formula: Gallons = (Length × Width × Height) / 231. This formula converts cubic inches to gallons, as 1 gallon equals 231 cubic inches.
The calculator uses the rectangular tank volume formula:
Where:
Explanation: This formula calculates the volume in cubic inches first, then converts to gallons using the standard conversion factor.
Details: Accurate volume calculation is essential for determining storage capacity, planning liquid containment, calculating fill times, and ensuring proper sizing for various applications in industrial, agricultural, and residential settings.
Tips: Enter all dimensions in inches. Measurements should be taken from the inside of the tank for internal volume. All values must be positive numbers.
Q1: Why divide by 231 specifically?
A: 231 is the standard conversion factor as one US liquid gallon is defined as exactly 231 cubic inches.
Q2: Can I use different measurement units?
A: This calculator requires inches as input. For other units, convert to inches first (1 foot = 12 inches, 1 cm = 0.3937 inches).
Q3: Does this work for irregular shapes?
A: No, this formula is specifically for rectangular prisms. Different formulas are needed for cylindrical, spherical, or irregularly shaped containers.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your measurements and how closely your tank resembles a perfect rectangular prism.
Q5: What about tank thickness?
A: This calculator computes internal volume. For external volume, measure outside dimensions and subtract wall thickness if needed.
