Formula
Variables
- L — Length (m)
- W — Width (m)
- H — Water depth (m)
Worked example
With length = 2 m, width = 1.5 m, water depth = 1.2 m, the calculator gives volume ≈ 3,600 litres; volume ≈ 3.6 m³.
Frequently asked questions
What is the rectangular tank volume calculator used for?
Find the water volume in a rectangular tank in litres and cubic metres. It helps with questions such as “rectangular tank capacity”, “litres in tank”, “tank volume calculator”.
What is the formula for the rectangular tank volume calculation?
Volume (litres) = L × W × H × 1000. Volume (m³) = L × W × H. Here L is length (m), W is width (m), H is water depth (m).
What inputs do I need for the rectangular tank volume calculator?
You need length in m, width in m, water depth in m. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the rectangular tank volume calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the rectangular tank volume result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
