Build a request or correction message

Choose what you need to report, enter the useful details, and generate a structured message. Nothing is submitted automatically: you review the text, then copy it or open it in your own email app.

What do you need help with?

Specific inputs, outputs, page links and sources make it much easier to investigate a problem or evaluate a useful calculator idea.

Complete the fields, then generate a message you can review.

What makes a useful request

Describe the user’s decision, the information they already have, and the result that would change what they do next. A product page, government guide, standard, or worked example is especially helpful.

What happens next

Messages may be used to correct a page, update a source, or evaluate a new tool. A reply is not guaranteed, and calculator requests are not promises of development or publication.

Before reporting a result

Check units, presets, fill percentages, editable assumptions and whether the page reports water-only weight or a complete loaded system. The FAQ explains common differences.

Not an emergency channel. Do not use this page for urgent medical needs, flight operations, severe weather, evacuation instructions, legal deadlines, financial transactions, or official government matters. Contact the appropriate emergency service, authority, provider, or qualified professional.
