About voltage units
Voltage is the difference in electric potential that drives current through a circuit. Sensor outputs are measured in millivolts, mains supplies in volts, and transmission lines in kilovolts.
Voltage prefixes scale the same electric potential difference. A unit conversion preserves whether the reported voltage is RMS, peak, peak-to-peak or DC.
