Watts to kVA Calculator

What is a Watts to kVA Calculator?

A Watts to kVA Calculator is a tool that converts real power (Watts) to apparent power (kVA) 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 kVA is:

\[kVA = \frac{Watts}{Power Factor \times 1000}\]

Where:

• kVA is apparent power in kilovolt-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 (kVA), real power (Watts), and reactive power (kVAR):

In this triangle:

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