About Naveen
Naveen P N is the founder and editor of AI Calculator (aionlinecalculator.com), a free suite of 157 standards-verified engineering, scientific, financial, health and programmer calculators used worldwide. He is the engineer behind every calculator on the site — designing, implementing, and reviewing each tool against the source standard before it ships.
Editorial responsibility
Naveen personally reviews every engineering calculator on the site. The review process for each tool is:
- Identify the governing standard (IEC, NEC, BS, AS/NZS, ASME, ACI) and the exact section / table that defines the calculation.
- Translate the published formula into JavaScript, preserving units and edge-case behavior.
- Test against worked examples from the standard's handbook (or, for older standards, from authoritative engineering references such as the IEEE Color Books, NEC Handbook, or AISC Steel Construction Manual).
- Test boundary cases (zero, negative, extreme values) — either return a sensible result or warn that the case is outside the validated range.
- Cite the standard and section number on the calculator's landing page.
Standards Naveen reviews against
- Electrical: IEC 60364 (low-voltage installations), IEC 60909 (short-circuit currents), NEC NFPA 70 (United States), BS 7671 (UK / IET 18th Edition), AS/NZS 3008.1.1 (Australia / New Zealand cable selection).
- Mechanical: ASME pressure vessel and piping codes, Darcy-Weisbach for pipe flow, standard psychrometric and HVAC load methods.
- Civil: ACI 318 (concrete), AISC Steel Construction Manual (steel design), standard geotechnical methods for soil bearing and slope stability.
- Health: WHO BMI ranges, Mifflin-St Jeor BMR equation, US Navy method body fat (referenced from Department of Defense Instruction 1308.3).
Why this page exists
Modern search engines and AI answer engines (Google, ChatGPT, Perplexity, Claude, Gemini) weight content more highly when an identifiable, accountable person stands behind it. This page is here so anyone — search-engine crawler, AI agent, or human reader — can verify who is responsible for the calculations on AI Calculator and how they are reviewed.
