Capacity Calculator
Use this tool to estimate the total internal volume of your fuel storage tank. Whether you’re planning a new installation or checking existing capacity, this calculator provides a quick and easy way to work out approximate tank volume from key dimensions.
Just choose the tank shape, enter your internal measurements, and select the output unit that suits your needs. This tool supports both rectangular and cylindrical tanks.
Safety Note
This calculator provides approximate volume only and should not be used as a substitute for certified tank calibration. Results may vary depending on wall thickness, tank end shapes, or internal structures. Always consult an expert before making operational or safety critical decisions.

Frequently Asked Questions
What shapes does the calculator support?
The calculator currently supports rectangular and horizontal cylindrical tanks, the two most common shapes used for fuel storage.
Should I use internal or external measurements?
Always use internal dimensions to get a more accurate estimate of usable fuel volume. External measurements will overestimate capacity.
Can I use this for water or other liquids?
Yes. The tool calculates geometric capacity and can be used for any liquid. However, it does not account for differences in density, expansion, or compatibility with specific materials.
