PF = Power Factor

Watts to VoltAmpere Calculator Calculator Usage Guide

Learn how to use the Watts to VoltAmpere Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the power in watts (W) in the first input field.
  2. Enter the power factor (PF) in the second input field. The power factor is a dimensionless number between 0 and 1 that represents the ratio of real power to apparent power.
  3. Click the "Calculate" button to compute the apparent power in volt-amperes (VA).
  4. The result will be displayed in the "Apparent Power (Volt-Ampere)" field.

Understanding the Formula

The formula used in this calculator is:

VA = W / PF

Where:

  • VA is the apparent power in volt-amperes.
  • W is the power in watts.
  • PF is the power factor.

Example

If you have a device that consumes 500 watts (W) and has a power factor of 0.8 (PF), the apparent power (VA) can be calculated as follows:

VA = 500 W / 0.8 = 625 VA

Applications

This calculator is useful for electrical engineers, technicians, and anyone working with electrical systems to determine the apparent power required for a given real power and power factor.
