A complete electrical engineering calculator suite in your pocket — Ohm's Law, reactance, trace width, and more. No ads, no subscription, no nonsense. Pocket Workbench is a complete electrical engineering calculator suite built for engineers, technicians, students, and hobbyists — the tools you actually reach for at the bench, in the field, or mid-design. No ads. No subscription. No account required. Just the calculators you need, done right. CORE CALCULATORS Ohm's Law solver — instantly solve for voltage, current, resistance, or power from any two known values Voltage divider calculator Reactance & resonance — capacitive reactance, inductive reactance, and LC resonant frequency RC/RL time constants — including capacitor charging voltage over time PCB trace width calculator — IPC-2221 standard, internal/external layers, any copper weight Series/parallel resistor & capacitor combinations Delta (Δ) ↔ Wye (Y) network converter LED series resistor calculator Capacitor stored charge & energy SMD resistor code decoder (3/4-digit and R-notation) dB power ratio, voltage ratio, and dBm ↔ watts converters Skin depth calculator with material presets Battery life estimator COMPONENT SCANNER (bonus feature) Point your camera at a resistor, inductor, or capacitor and Sohm will attempt to read its value automatically — color bands for resistors and inductors, printed codes for capacitors. This feature is actively improving; the calculators above are the reliable core of the app. Built for real work: clean interface, fast input, accurate formulas — nothing you have to dig through menus to find. Whether you're laying out a PCB, sizing a trace, decoding a resistor, or just double-checking Ohm's Law at 2am, Pocket Workbench has it covered.
