Editorial & Verification Policy

1. Editorial Independence & Purpose

Nm to Joules is an independent digital engineering and educational reference platform. Our singular technical objective is to clarify the physical, dimensional, and practical distinctions between torque (vector moment, measured in N·m) and mechanical work/energy (scalar quantity, measured in Joules).

All editorial content, reference matrices, and computational algorithms are created without commercial bias from tool manufacturers, automotive OEMs, or commercial sponsors. Where advertising or affiliate links appear, they are clearly labeled and do not influence calculation algorithms or editorial standards.

2. The 4-Stage Calculation Verification Protocol

Before any interactive calculator, conversion matrix, or formula derivation is published live, it must pass a rigorous four-stage quality assurance protocol:

1. First-Principles SI Derivation: All equations are decomposed into fundamental SI base units (kg, m, s) to ensure exact dimensional homogeneity ([M][L]²[T]⁻²).
2. Primary Standard Cross-Referencing: Formulas must conform directly to published standards from the International Bureau of Weights and Measures (BIPM), the National Institute of Standards and Technology (NIST SP 811), and the International Organization for Standardization (ISO 80000-4).
3. Algorithmic Unit Testing: Client-side JavaScript solvers are tested against published reference benchmark tables (e.g., ISO 898-1 proof stress tables and Bickford bolted joint empirical data).
4. Boundary & Failure Mode Analysis: Interactive solvers include real-world caveats, such as the limits of the short-form torque equation (T = K·F·d), bolt stretch tolerances, and material yield risks.

3. Sourcing & Citation Hierarchy

We rely strictly on established primary and secondary scientific sources:

• Tier 1 (Primary Standards): BIPM SI Brochure (9th Edition, 2019), NIST Special Publication 811 (Guide for the Use of the SI), and CODATA 2018 Fundamental Physical Constants.
• Tier 2 (Engineering Codes): ISO 898-1 (Mechanical properties of fasteners), VDI 2230 Part 1 (Systematic calculation of high-duty bolted joints), and ASME B1.1 (Unified Inch Screw Threads).
• Tier 3 (Automotive & Industry Standards): Tire Industry Association (TIA) ATS manual, SAE J398, and manufacturer OEM service manuals.

We do not cite unverified blogs, content farms, or tertiary aggregate encyclopedias without validating against original primary publications.

4. AI Transparency & Content Generation Policy

We believe in full transparency regarding computational and generative AI tools:

• All mathematical formulas, unit conversion ratios, and physical constants are derived from published metrology standards and verified manually.
• Generative AI models are strictly limited to assistive drafting, CSS styling optimization, and code linting under direct human engineering direction.
• No AI-generated text is published without human editorial review against authoritative standards. We never use AI to fabricate credentials, generate synthetic customer reviews, or invent test data.

5. Public Corrections Policy & SLA

Accuracy is the cornerstone of engineering trust. When a calculation discrepancy, typographical error, or updated standard is reported:

• Acknowledgment: All submitted technical inquiries are logged and reviewed within 24 to 48 business hours.
• Investigation: Our technical team re-evaluates the formula against primary NIST/ISO documentation.
• Correction: Confirmed errors are patched immediately on live solvers and noted in our public changelog below.
