What is a Watts to VA Calculator?

A Watts to VA Calculator is a tool that converts real power (Watts) to apparent power (VA) using the power factor. It helps in understanding the relationship between these two power measurements in electrical systems.

The Formula

The formula for converting Watts to VA is:

\[VA = \frac{Watts}{Power Factor}\]

Where:

  • VA is apparent power in volt-amperes
  • Watts is real power in watts
  • Power Factor is a dimensionless number between 0 and 1

Power Triangle

The power triangle visually represents the relationship between apparent power (VA), real power (Watts), and reactive power (VAR):

Real Power (Watts) Apparent Power (VA) Reactive Power (VAR) θ

In this triangle:

  • The hypotenuse represents apparent power (VA)
  • The adjacent side represents real power (Watts)
  • The opposite side represents reactive power (VAR)
  • The angle θ is the phase angle between voltage and current
  • The cosine of θ is the power factor
