kVA to Watts (W) Calculator

Real power in watts:

Calculation Formula

P(W) = 1000 × S(kVA) × PF

Where:

  • P(W) is the real power in watts
  • S(kVA) is the apparent power in kilovolt-amps
  • PF is the power factor (a dimensionless number between 0 and 1)

How to Convert kVA to Watts

To convert from kilovolt-amps (kVA) to watts (W), you need to know the power factor (PF) of the electrical system.

The real power P in watts (W) is equal to 1000 times the apparent power S in kilovolt-amps (kVA), multiplied by the power factor PF:

Example Calculation

What is the real power in watts when the apparent power is 3 kVA and the power factor is 0.8?

P = 1000 × 3kVA × 0.8 = 2400W
