What signing a guide means

Choosing the method

Defining the shape that represents the real case, the measurements it needs, and when an approximation is no longer sufficient.

Checking the calculation

Repeating worked examples, retaining intermediate precision, and validating units before publication.

Stating the limits

Keeping geometric, usable, and operating capacity separate, with every allowance and assumption made visible.

Maintaining each market

Adapting units, examples, and terminology for Spanish, English, and German readers instead of relying on literal translation.

How the work is supported

Automated tests help catch errors in formulas, routes, links, accessibility, and production builds. They do not replace editorial judgment: every method, example, source, and limitation must remain defensible to the reader.

Independence and funding

The calculators and guides are free to use. The project may be funded by advertising that is clearly separated from content and calculator controls. Advertisers do not choose formulas, conclusions, or editorial recommendations.

What this authorship does not claim

A signed geometric estimate is not an engineering design, official calibration, or advice on structures, pressure, health, hazardous substances, or regulatory compliance. Manufacturer information, applicable rules, and qualified advice take priority in those cases.

Corrections are welcome

When reporting an error, include the URL, dimensions, unit, and expected result. Substantive corrections receive a genuine editorial date; established URLs are not changed merely for convenience.
