Editorial Standards & AI Disclosure

Who is responsible for this content

Rick Oosterling is the author and sole editor of CovertItAll. Rick is based in the Netherlands and builds the tools he actually uses: electronics bench calculations, 3D printing settings, EV charging estimates and everyday unit conversions. The site covers the areas where he has direct practical experience, not a general topic list assembled to fill a catalogue.

The contact address for editorial matters is on the contact page.

How pages are built

Every tool page on CovertItAll follows the same structure by design: the converter or calculator sits at the top so you can get your answer without reading anything. Below the tool there is a short explanation of the conversion factor or formula, a worked example, and practical context for when the unit matters in real use. FAQ sections address the questions that come up repeatedly when working with that unit.

Hub pages group tools by task area: 3D printing, electronics, EV charging, solar, electrical work, and so on. The goal is that someone doing a real job can find every relevant tool without hunting across the site.

Pages are updated when conversion standards change, when a tool is identified as inaccurate, or when user feedback points to a genuine gap. The date shown on each page reflects the last substantive content update, not the publish date.

AI assistance

Content on this site is produced with AI writing assistance (Claude by Anthropic). This is an honest disclosure, not a disclaimer: the AI is used to draft and structure explanatory text; the editorial judgment on accuracy, relevance, tone and usefulness is Rick's. Every page is reviewed and edited before publication.

The calculator and converter logic is not AI-generated. The conversion factors, formulas and JavaScript behind each tool are written and verified by Rick against the sources listed below. The AI assists with prose; it does not determine the numbers.

Where AI drafts are used, the standard applied is the same as for manually written content: the explanation must be accurate, specific to the unit or tool on that page, and useful to someone doing a real task. Generic filler is edited out before publication.

Sources and fact-checking

Conversion factors on this site come from primary standards sources wherever they exist:

• SI units and physical constants: BIPM (Bureau International des Poids et Mesures) and NIST (National Institute of Standards and Technology) reference data.
• Electrical and electronics values: IEC and IEEE standards; verified against multiple references for common bench calculations.
• EV and charging specs: manufacturer documentation and IEC 61851 / SAE J1772 / CHAdeMO / CCS standards.
• Nutritional values: USDA FoodData Central and European Food Safety Authority reference tables.
• Filament and 3D printing parameters: filament manufacturer datasheets and FDM printing references.

Where values are inherently approximate (live exchange rates, tire pressure guidelines, clothing size charts), the relevant page notes this and explains the source of the approximation.

Corrections policy

Accuracy matters. If you find a wrong conversion factor, a broken calculator, or an explanation that contradicts an authoritative source, please use the contact page to report it. Include the URL of the page and the specific value or claim you believe is wrong.

Verified errors are corrected promptly. Material corrections to factual content (wrong formula, wrong factor, misleading explanation) are noted at the top of the affected page with the correction date. Cosmetic or formatting fixes are not separately noted.
