EngineeringCalcX — Professional Engineering Calculations Made Easy

EngineeringCalcX is a premium, fully offline engineering calculator suite built for students, engineers, architects, electricians, mechanics, technicians, surveyors, and construction professionals. Instead of juggling a dozen different calculator apps, get dozens of real engineering tools, unit conversions, and reference formulas in one clean, modern app — no internet connection required, ever.

📏 Geometry & Volume
Calculate area, perimeter, volume, and surface area for squares, rectangles, triangles, circles, ellipses, polygons, trapezoids, cubes, cylinders, cones, spheres, pyramids, and prisms.

⚖️ Mechanics
Force (Newton's Second Law), pressure (with Pa/kPa/MPa/bar/PSI conversions), torque, density, and speed calculators — all with real, verified formulas.

⚡ Electrical
Ohm's Law (solve for voltage, current, or resistance), power calculations (V×I, I²R, V²/R), energy consumption, battery runtime estimation, LED resistor sizing, and conductor voltage drop.

📐 Structural & 🏗️ Materials
Beam load analysis, column load capacity, concrete volume, brick estimation, steel rebar and pipe weight, plus material estimators for cement, sand, gravel, paint, tiles, and flooring — using standard construction industry formulas.

🔄 Unit Converter
Convert between units across Length, Weight, Force, Pressure, Energy, Power, Speed, Torque, Volume, Density, Area, Data Storage, and Temperature — with a one-tap swap and a log of recent conversions.

📚 Formula Library
A searchable reference library of Mathematics, Physics, Civil, Mechanical, Electrical, and Construction formulas — each with a plain-language explanation, variable definitions, and a fully worked numeric example.

⭐ Favorites, 🕘 History & 📊 Statistics
Star your go-to calculators and formulas, automatically save every calculation you run, and track your usage with a personal statistics dashboard — all stored privately on your device.
