Formula-backed answers for controls work.

Convert raw input counts to engineering units

Solve voltage, current, resistance, and power from two known values

Estimate single-phase or three-phase load current from kW, voltage, and power factor

Plan masks, usable hosts, broadcast, and ranges

Forward and inverse scaling across raw counts, live-zero signals, percentage, and engineering units

Estimate rotating energy, average braking torque, power, and review cautions

Build a local load list with inrush, utilization, and design margin

Estimate voltage drop for copper or aluminum DC, single-phase, and three-phase circuits

Normalize clock offsets, sort events, calculate elapsed time, and export a timeline

Use the free Ohm's Law and current calculators, then unlock power, motors, voltage drop, wire, transformer, fuse, and breaker workflows.
