Kilovolt-Amperes to Kilowatts Converter
How to Convert Kilovolt-Amperes (kVA) to Kilowatts (kW)
Converting kilovolt-amperes (kVA) to kilowatts (kW) depends on the power factor (PF) of the electrical system. The formula is:
KVA to KW Calculation Formula
The real power P in kilowatts (kW) is equal to the apparent power S in kilovolt-amperes (kVA), multiplied by the power factor PF:
P(kW) = S(kVA) × PFThus, kilowatts are equal to kilovolt-amperes multiplied by the power factor:
kW = kVA × PFExample Calculation
If you have an apparent power measurement of 10 kVA and a power factor of 0.8, the calculation would be:
P(kW) = 10 kVA × 0.8 = 8 kWApparent Power (kVA)
Kilovolt-amperes (kVA) represent the total power supplied by the electrical system, including both real power and reactive power.
Real Power (kW)
Kilowatts (kW) represent the actual power consumed by a device, which performs useful work in an electrical system.
Power Factor (PF)
Power factor is the ratio between real power (kW) and apparent power (kVA). It indicates how effectively the electrical power is being converted into useful work.
Pro Tip
Always size your electrical systems based on kW (real power) rather than kVA (apparent power) to ensure your system meets actual power needs!
