Electrical power conversion

kW, kVA & Current Calculator

Convert between real power, apparent power and current for single-phase or three-phase loads using an entered power factor.

Enter your values

Example values demonstrate the method; they are not product recommendations.

Your result

Enter measured or nameplate values to calculate.

Method

kW = kVA × power factor. Apparent power is V × A for single-phase and √3 × line voltage × line current for balanced three-phase loads.

Important limits

Balanced-load screening only. Do not use the result to choose conductors, breakers, protection or equipment ratings.
