About EngiCalcul
Our Mission
EngiCalcul was created to provide engineers, students, and construction professionals with free, reliable, and easy-to-use engineering calculators. We believe that access to accurate calculation tools should not be limited by cost or complexity.
What We Offer
Our calculator library covers six major engineering disciplines:
- Structural Engineering — Beam deflection, column buckling, moment of inertia, steel beam design, truss analysis
- Concrete Design — Mix proportioning, volume estimation, rebar spacing, strength calculations, slab thickness
- Mechanical Engineering — Gear ratios, torque, belt drives, spring constants, thermal expansion
- Hydraulics & Hydrology — Pipe flow, Manning's equation, Bernoulli equation, rainfall-runoff, head loss
- Construction & Earthworks — Cut & fill volumes, earthwork estimation, soil compaction, slope stability, retaining walls
- Electrical Engineering — Ohm's law, power factor, voltage drop, wire sizing, transformer calculations
Key Features
- Step-by-step worked solutions for every calculation
- Support for both Metric (SI) and Imperial unit systems
- Engineering formulas with variable explanations
- Practical warnings for out-of-range values
- Referenced to recognized engineering standards (AISC, ACI, Eurocode, NEC)
- Frequently Asked Questions for each calculator
- No registration required — completely free to use
