Free calculators and analyzers built specifically for mechanical, electronics packaging, and avionics engineers. Real equations. Real standards. Real results.
Every tool implements the actual engineering equations — not approximations. AI adds context, warnings, and methodology notes.
AI-assisted random vibration analysis using the Miles Equation. Input your PSD profile and natural frequency to compute GRMS acceleration loads. Includes MIL-STD-810H profiles, Q factor guidance, and AI-generated methodology notes for your analysis report.
Open calculatorAI-powered torque specification tool covering MMPDS, ASME B1.1, ISO 724, and IFI-100. Calculates installation torque for aerospace-grade fasteners with material and lubrication corrections. AI explains the rationale behind each value.
Open calculatorInstant ANSI/ASME B18.2.8 clearance hole lookup for any fastener size. Covers close, normal, and loose fit classes for inch and metric. AI tells you which fit class to use based on your application and tolerance requirements.
Open toolComprehensive unit conversion for mechanical engineers. Stress, pressure, force, torque, temperature, frequency, and vibration units. AI context explains which unit system is standard in aerospace, automotive, and defense applications.
Open converterThese tools weren't made by a software team — they're built by a working aerospace mechanical engineer with over a decade of hands-on experience designing avionics enclosures, running random vibration analysis, and delivering flight hardware to defense programs.
Every equation is checked against real engineering judgment. Every standard reference is verified. This site exists because engineers deserve better tools than legacy spreadsheet macros.
