Engineering calculator: scientific keypad, unit converter, graphs and formulas
Engineering calculator and scientific calculator in one app: a unit converter with 24 categories, function graphs, 34 ready calculators for electrical, construction and mechanics work, and a formula library. Built for students, engineers, electricians and builders who need the answer on the spot. WHO IT'S FOR: - Students and teachers: scientific calculator, equation solver, graphing calculator and a formula library for study and exams. - Engineers and technicians: unit converter, matrices, vectors, complex numbers and mechanics helpers for daily work. - Electricians: electrical calculator for Ohm's law, voltage drop, cable sizing, breaker choice, three-phase power and resistor color codes. - Builders: construction calculator for concrete, tile, paint, plaster, brick, slope and stairs on site. - Mechanics and programmers: torque, gears, springs, plus BIN/OCT/DEC/HEX and bit operations. CALCULATOR MODES (9) Basic, scientific, engineering, programmer, RPN, matrix, vector, complex and equation solver. ANS, memory, constants, powers, roots, logarithms, factorials, percentages and degree/radian trigonometry. PROGRAMMER CALCULATOR BIN/OCT/DEC/HEX, signed and unsigned values, 8/16/32/64-bit modes, AND/OR/XOR/NOT, shifts, rotates, ASCII/Unicode, Unix time, Base64 and URL tools. UNIT CONVERTER (24 CATEGORIES) Length, area, volume, mass, temperature, pressure, energy, power, speed, acceleration, force, density, torque, flow, angle, voltage, current, resistance, capacitance, inductance, time, frequency, data and fuel consumption. Add your own linear units and keep favorite pairs one tap away. ELECTRICAL CALCULATOR Ohm's law, voltage drop, voltage divider, series and parallel resistance, current divider, three-phase power, cable sizing, breaker selection, LED resistor, RC/RL time constants, decibels, resistor color code and RLC circuits. CONSTRUCTION CALCULATOR Concrete, room, tile, paint, plaster and brick quantities, slope and stairs. Plus mechanics, physics, chemistry and geometry: torque, gear ratio, spring force, beam deflection, friction, traction power, kinematics, work, energy, momentum, density, ideal gas and pH. GRAPHING CALCULATOR Plot several functions at once, zoom and pan, read values, find roots, minima and maxima, estimate derivatives and integrals, find intersections, export SVG and save the result into a project. FORMULAS AND PROJECTS A library of ready formulas, favorites, and your own reusable formulas with variables. History with search, notes and tags; projects and templates; CSV, PDF and text export; encrypted local backup and restore. COMFORT Themes, AMOLED mode, high contrast, haptics, precision settings and 14 interface languages. WHERE YOUR DATA LIVES Calculations, history, projects and backups are stored in the app on your device. The calculator, converter, graphs and tools run without a network connection. Google Play handles purchases and the rating prompt, so those two need the internet. FREE AND PRO Free: every calculator mode, the whole unit converter, graphs, all 34 tools, the formula library, 250 history entries, one project, 5 of your own formulas. Pro, through Google Play (monthly, yearly or one-time): unlimited projects and history, your own units, keyboard macros, backup versions, advanced graph presets, exports, themes and templates. Important: results are estimates and helper calculations. Critical engineering, electrical, construction, chemical or safety-related work must be verified with certified tools, current standards, manufacturer specifications and qualified professionals.
