Watts to Kilovolt-Amps Converter
How to Convert Watts to Kilovolt-Amps (kVA)
To convert watts (W) to kilovolt-amperes (kVA), you need to know the power factor (PF), which is the ratio of real power (watts) to apparent power (volt-amperes). The power factor indicates how effectively the current is being converted into useful work output. A power factor of 1 means all the power is being effectively converted, while lower values indicate less efficiency. The formula for W to KVA conversion is:
Watts to kVA Calculation Formula
The apparent power S in kilovolt-amps (kVA) is equal to the real power P in watts (W), divided by the power factor PF:
S(kVA) = P(W) / (PF × 1000)Thus, kilovolt-amps are equal to watts divided by the power factor and then divided by 1000:
kVA = W / (PF × 1000)Example Calculation
If you have a power measurement of 1000 watts and a power factor of 0.8, the calculation would be:
S(kVA) = 1000 W / (0.8 × 1000) = 1.25 kVAFor more information on watts, visit the Wikipedia page on Watts.
