Calculation Portal Support
Contact Calculation Portal
Have a question about a calculator, spotted a possible error, want to suggest a new calculation tool, or need to contact us about the educational content on Calculation Portal? Use this page to send us the details. Clear, specific feedback helps us investigate technical questions more efficiently and continue improving the accuracy, usability, and educational value of the site.
How Can We Help?
Calculation Portal provides calculators and educational resources intended to make mathematical, scientific, engineering, financial, conversion, and other quantitative topics easier to understand. A calculator may look simple on the surface, but a useful result can depend on formulas, definitions, units, assumptions, rounding rules, reference values, and the way individual inputs are interpreted. Because of that, detailed feedback from users is valuable. If you believe a result is unexpected, please tell us which calculator you used, which values you entered, which units you selected, and what result you expected. That information gives us a much clearer starting point for reviewing the issue.
You can also contact us about written guides, formulas, terminology, broken links, accessibility, usability, or ideas for new calculator categories. If your message concerns factual or mathematical accuracy, include a reputable source whenever possible. Useful references may include government publications, recognized standards organizations, universities, peer-reviewed research, professional bodies, manufacturer documentation, or other authoritative technical material.

Reasons to Contact Calculation Portal
We encourage useful feedback that can improve calculations, explanations, navigation, or the overall experience of using the site. Selecting the most relevant contact category and including enough technical detail helps us review the message efficiently.
How to Report a Possible Calculator Error
A message that simply says a calculator is “wrong” can be difficult to investigate because the same equation may return different results depending on units, assumptions, constants, rounding, or input definitions. When reporting a suspected error, provide the exact values entered into every relevant field and identify the unit selected for each value. Copy the result displayed by the calculator and explain what result you expected instead.
It is also helpful to identify the source supporting the expected method. Different industries sometimes use equations that look similar but are based on different conventions. Supplying an authoritative reference helps distinguish a software problem from a difference in definitions or modeling assumptions.
How to Suggest a New Calculator
Calculator suggestions are most useful when they describe a clear problem rather than only naming a broad subject. Identify the quantity a user needs to determine and the variables normally used to calculate it. If you know the governing equation, include it. It is also helpful to identify expected input and output units, typical ranges, assumptions, standards, or external reference data.
We may consider whether a proposed calculator has a clearly defined purpose, can be explained accurately, uses information that users can reasonably provide, and can communicate its limitations without creating a misleading impression of precision.
Editorial and Educational Content Feedback
Calculation Portal articles are intended to explain the concepts behind calculations rather than merely display equations. If an explanation is difficult to understand, appears incomplete, uses a term without defining it, or does not make an assumption clear, identify the relevant page and section.
For factual corrections, distinguish between a preference in wording and a statement that is technically incorrect. When more than one established convention exists, the appropriate solution may be to explain the distinction rather than replace one version with another.
What Happens After You Contact Us?
Messages may require different levels of review depending on their subject. Providing a complete initial report can substantially improve this process.
Your Message Is Reviewed
The information supplied through the contact form is examined to identify the relevant calculator, article, technical issue, or administrative matter.
Technical Details Are Checked
Where appropriate, formulas, units, calculations, constants, assumptions, source references, or website behavior may be checked against the reported issue.
A Correction May Be Made
If a genuine issue is confirmed, the relevant calculation, wording, interface, link, explanation, or supporting content may be updated as appropriate.
Further Information May Be Requested
If the issue cannot be reproduced or essential details are missing, additional information may be needed.
Contact Page Frequently Asked Questions
What information should I include when reporting an incorrect calculator result?
Include the calculator name or URL, every input value, the unit selected for each input, the result displayed, and the result you expected. If possible, provide the formula or authoritative reference used to obtain your expected result.
Can I request a calculator that is not currently on the site?
Yes. Describe what the proposed calculator would calculate, which inputs users would provide, which outputs it should return, and the mathematical or technical method behind it.
Can Calculation Portal verify my professional calculation?
The site provides educational and general-purpose calculation resources, not individualized professional certification or approval. Decisions requiring licensed professional judgment, regulatory compliance, certified data, or safety-critical analysis should be reviewed by an appropriately qualified professional.
What sources are useful when submitting a technical correction?
Strong sources include official government publications, recognized standards organizations, universities, professional or scientific organizations, peer-reviewed research, original technical documentation, and authoritative manufacturer references.
Should I send passwords or sensitive account information?
No. Do not submit passwords, complete payment-card details, government identification numbers, confidential medical records, private financial credentials, authentication codes, or other information that is not reasonably necessary to explain your inquiry.
Can I report an accessibility problem?
Yes. Describe the page or component involved, what you were attempting to do, the problem encountered, and any assistive technology or browser information that may help reproduce it.
Can I contact Calculation Portal about copyright or intellectual property?
Yes. Select the appropriate contact category and provide enough information to identify the material concerned, including the relevant Calculation Portal URL and a clear explanation of the issue.
Privacy When Contacting Us
Only provide information that is reasonably necessary for us to understand your inquiry. Contact forms are not appropriate places for passwords, financial account credentials, full payment-card details, government-issued identification numbers, highly sensitive personal records, or confidential information belonging to another person or organization.
