Power Converters: Watts, Amps and Volts
Convert between electrical power, current and voltage using each tool's stated inputs and formula. The steps stay on the page.
Amps to watts
Convert amps to watts for DC, single-phase, and three-phase. The steps use volts and power factor. The result is real power in watts, not volt-amperes.
Volts to watts
Convert volts and amps to watts for DC, single-phase, and three-phase. The steps use power factor on AC. The result is real power, not volt-amperes.
Watts to amps
Convert watts to amps for DC, single-phase AC or balanced three-phase loads. Enter voltage and power factor, then follow the calculation steps.
Watts to volts
Find volts from watts and amps for DC, single-phase, and three-phase. The steps use power factor on AC. Three-phase results are line-to-line volts.
