What we publish
NumberTrove publishes practical calculators, conversion references, number profiles, guides, and learning activities. Each page should make its purpose, inputs, formula or method, assumptions, limitations, and useful next step visible.
Sources and review
External facts, rates, standards, health classifications, and financial or tax claims require an identifiable source and a review date. Generated calculations must be deterministic and covered by tests. We do not invent authors, credentials, citations, or first-hand experience.
Corrections and updates
When an error is reported, the page owner reproduces it, identifies whether the issue is content, formula, data, or presentation, and records the correction before publishing. Material formula or source changes update the reviewed date and receive regression coverage. Low-value or obsolete pages may be consolidated, redirected, or removed from the index rather than left as thin content.
Independence and disclosures
Commercial relationships, partner resources, advertising, and affiliate links must be labeled and kept separate from calculator results and editorial judgments. A partner cannot purchase a favorable formula, ranking, review, or recommendation.
