Editorial Policy
<h2>How pages are written</h2>
Every calculator page follows the same structure: what it does, the formula in plain language, how-to steps, a worked example, common mistakes, limitations and FAQs. Wording is written originally for each tool.
<h2>Formula standards</h2>
Calculators implement standard published formulas. Where a simplification is used, the page says so in its limitations section.
<h2>Review process</h2>
Pages carry a last-reviewed date. The formula library is covered by automated tests that check known inputs against expected outputs.
<h2>Corrections</h2>
If you spot an error, contact us with the page URL and details. Verified corrections are fixed promptly and the review date is updated.
<h2>Advertising</h2>
If the site shows ads, they are clearly separate from calculator content and do not influence results.
