Contact Tank Calculator

A result you don’t understand, a volume or weight figure that looks wrong, a dip-chart row that disagrees with your calibration chart, a feature you wish existed, or a partnership idea — this page routes your message to the person who can actually help. Every calculation question is answered by someone who can re-run the math and check your numbers.

Calculation & Results Support

A volume or weight figure not matching what you expected? Send your inputs — tank shape, dimensions, head type, fill depth, liquid selection, and tilt if used, plus any Advanced Options you changed (unit system, custom density, dip increment) — along with the result you expected versus the result returned.

Corrections

Report a Formula or Data Error

Our engine runs the geometry for 10 tank shapes, the dish-end corrections (flat, hemispherical, 2:1 elliptical, torispherical), the dip-chart integrator, liquid density and weight conversion, tilt correction, and unit conversion. If any output, preset, or guide statement disagrees with your hand calculation or the calibration chart, send the page URL and the exact numbers. We verify before changing anything.

Feature Requests & Ideas

Want more tank shapes, finer dip-chart increments, printable strapping tables, additional liquid presets, tilt entry by elevation difference, or a printable gauge table export? We build around what tank operators, haulers, and process engineers actually need on the job.

Partners

Partnerships & Trade Education

Distributors, tank fabricators, trade schools, apprenticeship programs, and fuel, agricultural, or process-industry associations — we are open to white-label licensing, classroom integrations, printed reference companions, and co-developed estimating tools.

What Happens After You Hit Send

No ticket numbers, no canned macros. Here is the actual path a message takes from your outbox to a verified answer.

  1. Step 1

    We Read It

    A person reads your message — not a ticket bot. Messages with exact inputs (shape, dimensions, head type, fill depth, liquid or density, unit system) jump straight to the front of the queue.

  2. Step 2

    We Recompute It

    For anything numeric, we re-run the geometry × depth × density math by hand and compare against the calibration chart or the reference source before we answer. Most volume questions are resolved in a single reply.

  3. Step 3

    We Answer With the Math Attached

    You get the explanation, the formula behind it, and — where relevant — the input to change. If we were wrong, the reply says so plainly and the fix is dated on the page it affects.

  4. Step 4

    We Keep the Receipt

    Verified corrections and good feature requests feed directly into the roadmap. Your email stays with the thread and is never added to any list — there are no lists.

Quick Answers

The five questions we hear most from tank operators, haulers, and DIYers.

How do I get a faster reply?

Include the exact inputs you entered — tank shape, dimensions, head type, fill depth, liquid or custom density, tilt if used, and any advanced options such as unit system or dip increment — plus the result you expected and the result the calculator returned. That single message usually lets us reproduce and explain the difference in one reply.

Do you offer live chat or phone support?

Not yet. Email lets us verify every answer against the actual geometry-and-density math and the published reference tables before responding, which matters when the topic is payload plans, pad loads, and purchase-order volumes. We read every message and answer most within two business days.

Can you tell me which tank to use for my job?

We can explain what the numbers mean — how a head-type change moves the capacity, why diesel and water differ at the same fill, how the tilt correction behaves — but tank selection for a specific service belongs to the design code, the manufacturer's data, and a qualified engineer. Venting, foundation design, and code compliance are engineering decisions, not calculator outputs.

Do you sell tanks, fittings, or tools?

No. The site sells nothing, carries no affiliate links, and is not affiliated with any fabricator or distributor. Advertising is clearly labeled and separately handled — see the advertising section of the Privacy Policy for how that works.

Can I suggest a topic for the guide library?

Please do — that is exactly how the library grows. Send the question you were trying to answer, the job you were working on, and what you wished had been written down. Requests that describe a real job-site problem go to the top of the content queue.

What to Include for a Fast Reply

  1. 1Browser & device (for UI glitches)
  2. 2Exact inputs: tank shape, dimensions, head type, fill depth & liquid — plus custom density, tilt, or increment if changed
  3. 3The result you expected vs. the result shown
  4. 4Page URL or section title if a dip chart, preset, or guide looks wrong

Attach a screenshot of your calculator inputs if you can — it halves the back-and-forth.
