kVA to kW calculation

The value of the real power P which is measured in kilowatts (kW) is apparently equal to the value apparent power S in kilovolt-amps (kVA), multiplied by the power factor PF.

P(kW) =  S(kVA) × PF

Convert kVA to kW

If you need to convert the apparent power in kilovolt-amps (kVA) to real power measured in kilowatts (kW).

kVA to kW calculation formula

The real power P in kilowatts (kW) is apparently equal to the value of apparent power S measured in kilovolt-amps (kVA), times the power factor PF.

P(kW) =  S(kVA) × PF

So, the value of kilowatts are equal to kilovolt-amps multiplied by the power factor.

kilowatts = kilovolt-amps × PF

or

kW = kVA × PF

For Instance,

If you need to find out the real power in kilowatts if the apparent power is 4 kVA and the power factor is 0.6?

Solution:

P = 4× 0.62.4

Percentage change calculation

The percentage change from old value (Vold) to new value (Vnew) is equal to the old and new values difference divided by the old value times 100%:

percentage change = (VnewVold) / Vold × 100%

Example #1

Price percentage increase from old value of 1000\$ to new value of 1200\$ is caluclated by:

percentage change = (1200\$ – 1000\$) / 1000\$ × 100%

= 0.2 × 100% = 20%

Example #2

Price percentage decrease from old value of 1000\$ to new value of 800\$ is caluclated by:

percentage change = (800\$ – 1000\$) / 1000\$ × 100%

= -0.2 × 100% = -20%
