Role & Responsibilities
As the lead developer and technical editor, my primary responsibility is the integrity of the calculation logic. This is not just a coding project; it is an engineering resource.
My work involves:
- Translating formulas from academic texts and industry standards into performant code.
- Designing computational stress tests to ensure calculators handle edge cases (e.g., Temperature effects on gas density).
- Maintaining the Editorial Policy to ensure all content meets strict verification standards.
- Personally reviewing calculator outputs against known reference values before release.
How Calculators Are Built & Verified
Every tool starts with a Literature Review. I do not rely on other online calculators as a source of truth. Instead, I reference primary documentation.
Once a formula is identified, it is implemented in TypeScript with strict typing to prevent unit errors. The code is then tested against known textbook problems to verify accuracy to significant figures. Each calculator is versioned and updated when reference standards or methodologies change.
Standards & References
The logic across this site is underpinned by standards from recognized international bodies, including:
- ASTM International (e.g., D-Series for Water)
- IUPAC (Chemical Nomenclature)
- EPA (Environmental Guidelines)
- NIOSH (Analytical Methods)
Transparency
Scope & Limitations:
While these tools are built for high accuracy, they are intended for education and preliminary estimation. They do not replace certified laboratory testing or regulatory compliance requirements.
