CalcSHQ Editorial

What we do

We source formulas from primary references (Wikipedia, NIST, peer-reviewed papers, government data), implement the calculator UIs, write the explanations and FAQs, and check every page before publishing.

Why this site exists

Existing calculator sites are bloated with ads, popups, and recycled GPT content. We wanted something fast, ad-free, and actually useful — calculators that teach you the formula, show worked examples, and link to authoritative sources.

How we verify content

• Every formula has a public reference (Wikipedia, NIST, ACI, ACSM, IEEE, or a named research paper).
• Worked examples are computed by hand and double-checked against the calculator output.
• FAQs cover the edge cases people actually ask about, not invented questions for keyword stuffing.
• AI-assisted drafts are always rewritten and fact-checked by a human before publishing.
• Each calculator page lists its content review date and links back to this page so readers know who stands behind the numbers.

Stack & ops

Next.js 16 with static export, Tailwind 4, KaTeX for formulas, FlexSearch for search. Hosted on a small VPS in Germany, served by Caddy. The entire site is static HTML — no databases, no server-side JS for the math, nothing sent to any third party when you use a calculator.
