Editorial Policy

Content Standard

Useful calculator pages must explain what the tool calculates, define inputs and outputs, show assumptions and limitations, provide reproducible examples, and cite relevant sources.

Formula Review

The review checklist compares the displayed formula, worked examples, input constraints, and cited source with the implementation. Time-sensitive tools require a fresh source check before their update date changes.

Corrections

Readers can report errors through the contact page. Verified calculation and source errors are prioritized over cosmetic changes.
