Electrical Calculation Formulas & Unit Conversion
Quickly convert Watts to Amps, calculate conductor sizes, and estimate voltage drops for electrical engineering projects.
Single-Phase Power: $P = V \cdot I \cdot \cos\varphi$
Three-Phase Power: $P = \sqrt{3} \cdot V \cdot I \cdot \cos\varphi$
Single-Phase Power: $P = V \cdot I \cdot \cos\varphi$
Three-Phase Power: $P = \sqrt{3} \cdot V \cdot I \cdot \cos\varphi$
How to convert Watts to Amps?
Divide Power in Watts by Voltage in Volts (and multiply by power factor for AC).
