What is a Square Storage Tank?
A square storage tank is a specialized rectangular container where the length and width of the base are equal. Square tanks offer maximum internal volume within square footprints, simplifying fabrication and modular stacking.
How This Calculator Works
Our square tank calculator takes the uniform side length of the square base and internal height, calculates the total geometric volume using Volume = Side² × Height, and automatically converts the result into Litres, US Gallons, Imperial Gallons, Cubic Feet, and Cubic Meters. For buried reservoirs or water collection pits, compare results with our sump tank capacity calculator or dedicated water tank volume calculator.
How to Use the Square Tank Volume Calculator
Calculating the capacity of a square storage tank is straightforward with these simple point-by-point steps:
- Enter Base Side Length: Input the internal edge length of your square tank base (e.g., in ft, in, m, or cm).
- Enter Tank Height: Input the internal depth/height from bottom to top fill line.
- Select Measurement Units: Choose your preferred input units (ft, in, m, cm) for both side length and height.
- Enter Optional Fill Depth: If your tank is partially filled, enter the current liquid fill depth.
- Click "Calculate Volume": Press the calculate button to instantly compute total storage capacity.
- View Point-Wise Results: Review exact volume conversions across US Gallons, Litres, Cubic Feet, Cubic Meters, and UK Gallons.
Square Tank Volume Formula
Square Tank Formula: Volume = Side² × Height
Where Side is the uniform base edge length and Height is the internal tank depth.
Step-by-Step Square Storage Tank Measurement
- Measure the internal edge length of the square base in feet, inches, centimeters, or meters.
- Measure the overall internal height from the container bottom to the overflow line.
- Multiply Side × Side × Height to obtain total cubic volume.
- Convert cubic volume into liquid capacity: 1 cubic meter equals 1,000 Litres or 264.172 US Gallons. Reference: Wolfram MathWorld Geometry Standards.
