Editorial Policy
Our editorial rules are designed to keep calculator pages useful to people first, while making formulas, assumptions, authorship, and sources visible.
Accuracy before keyword coverage
Search terms may shape headings and examples, but they do not change the underlying mathematics. We do not publish a neat-looking number when the conversion actually requires density, concentration, molecular weight, or another missing variable.
How content is prepared
- Identify the actual units and whether they measure the same physical quantity.
- Choose the correct conversion factor or required contextual variable.
- Build the forward and reverse formulas.
- Add worked examples and a reference chart where it improves understanding.
- Link the page to closely related calculators within the same silo.
- Review headings, definitions, FAQs, assumptions, source references, and metadata before publication.
Sources and attribution
We prefer primary measurement standards, official public-health or medicine-measurement guidance, and recognized scientific references. Competitor pages may help identify user questions or missing explanations, but another calculator site is not treated as the authority for a measurement definition when a primary source is available.
Medical and health-related content
Health-adjacent pages explain unit arithmetic, concentration, and measurement concepts. They do not prescribe a treatment or recommend a dose. Where qualified clinical review has not actually occurred, the site does not claim that it has.
AI-assisted drafting and human responsibility
Digital tools may be used to assist drafting, formatting, code generation, or quality checks. Published material remains the responsibility of the site publisher. Formula logic, assumptions, page structure, and source choices are reviewed before release.
Updates and corrections
Material may be updated when standards change, a better source becomes available, a formula or label is unclear, or a visitor reports a credible problem. Significant calculation corrections should be applied consistently to the calculator, examples, tables, and explanatory text.
