Power & Motor Calculator

Calculate common electrical power relationships from voltage, current, phase, power factor, and related inputs.

What this utility does

The Power Calculator provides preliminary electrical power calculations for the supported single-phase and three-phase relationships.

How to use

  1. Choose the calculation type that matches the available values.
  2. Enter the electrical quantities and units.
  3. Check the result and units, then compare it with the equipment nameplate or design calculation where applicable.

Practical notes

  • Power calculations depend on the selected phase system and power factor assumptions.
  • For real installations, use measured or manufacturer-specified values when they are available.
