Tank Dimension Calculator

If you’re working in construction, engineering, agriculture, manufacturing, or any industry that involves liquid or material storage, knowing the exact tank dimensions and volume is crucial. Whether you’re installing a new tank, replacing an old one, or just need accurate specifications for planning, our Tank Volume Calculator Tool provides instant and reliable calculations.

This online tool supports three main tank types—rectangular, cylindrical, and spherical. It helps you compute total volume, filled volume based on fill level, surface area, and material volume based on tank construction material. With just a few inputs, you’ll get detailed results in real-time—no manual math, no spreadsheets.

Let’s explore how to use the tool, its features, examples, and answers to frequently asked questions.

20 Most Common FAQs

1. What units are used in the tank calculator?

All dimensions are in meters, and volumes are calculated in cubic meters (m³) and liters.

2. Can I use this for fuel tanks?

Yes. The calculator can estimate fuel or any liquid tank volume.

3. Is the fill level mandatory?

No, but if you want to know the partial volume, you must set the fill level.

4. What’s the formula used for rectangular tanks?

Volume = Length × Width × Height

5. How is surface area useful?

It helps in estimating material needed for tank construction or coating.

6. Does it work for underground tanks?

Yes, as long as dimensions are known, the tank’s location doesn’t matter.

7. What’s the default thickness for materials?

  • Steel: 5 mm
  • Plastic: 8 mm
  • Concrete: 100 mm
  • Fiberglass: 6 mm

8. Can I use feet or inches?

Currently, the calculator only supports meters. You may convert feet/inches to meters first.

9. Is it accurate for irregular tanks?

No. It only calculates based on standard shapes: rectangular, cylindrical, and spherical.

10. Can I save the results?

You can screenshot or copy the data manually for records.

11. Does the tool consider tank wall thickness in volume?

No, volume is internal (usable). Wall thickness is only considered for material volume.

12. How is material volume estimated?

Material Volume = Surface Area × Thickness (based on selected material).

13. What is orientation in cylindrical tanks?

It refers to whether the cylinder stands vertically or lies horizontally.

14. Can I input decimal values?

Yes, you can use decimal values for precision (e.g., 1.25 meters).

15. What happens if I leave a required field empty?

The tool will prompt you to fill all required fields before calculating.

16. Does the tool work offline?

It requires a web browser but can work offline if the page is cached.

17. Is it free to use?

Yes, the calculator is completely free for all users.

18. Can I integrate it into my website?

Yes, but you must follow licensing and credit rules of the website owner.

19. What if I get a wrong or unexpected result?

Double-check the values and units entered. The tool only calculates based on inputs.

20. Can I use it for gas tanks?

Yes, for volume estimates. But remember gases are compressible—this tool doesn’t simulate pressure or gas behavior.
