Engineering Tools
Without Barriers
Professional-grade calculators and technical guides, free and open to every engineer on the planet. No signup walls. No paywalls. Just pure engineering excellence.
We believe engineering knowledge should be open, accurate, and accessible to every professional—regardless of location, language, or budget.
From a student calculating their first voltage drop to a senior engineer verifying a complex HVAC system—Enginist provides the tools, formulas, and documentation you need to do your best work.
What We Stand For
These principles guide every decision we make, from calculator accuracy to user experience.
Every calculator is benchmarked against IEC, ASHRAE, and EN standards with <2% deviation from reference values. We document assumptions and provide transparent formulas.
Engineering knowledge has no borders. Our platform is multilingual by design, ensuring professionals worldwide can access quality tools in their language.
No paywalls, no signup walls, no hidden costs. Professional engineering tools should be accessible to everyone—from students to senior engineers.
Every calculator comes with comprehensive documentation, worked examples, and standards references. We teach the 'why' behind every formula.
Built on International Standards
Every calculation references recognized engineering standards. We cite sources, document assumptions, and maintain traceability.
