Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.
Conversion Using the Power Formula :
AC Single Phase KVA to KW Calculation:
The Real power (P) in kilowatts (kW) is equal to the apparent power (S) in kilovolt-amps (kVA), times the power factor PF:
For example, let’s find the real power of a piece of equipment with 75 kVA of apparent power and a power factor of 0.9.
P(Kw) = 75 x 0.9
P(Kw) = 67.5
Where:
-
- P = Power in Kilowatts (kw)
- S = Apparent Power in Kilo-volt-amps (Kva)
- Cosθ = Power factor in AC circuits

Frequently asked questions
volt-ampere (VA) is the voltage times the current flow feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. Electrical Real power is measured in watts (W).
The power factor is an expression of energy efficiency. It is usually expressed as a percentage—and the lower the percentage, the less efficient power usage is. Power factor (PF) is the ratio of working Real power, measured in kilowatts (kW), to apparent power (VA), measured in kilovolt amperes (kVA).
A common industry standard generator's Real power factor rating is 0.8, or 80%, meaning these loads can use 80% of the generator's power supply.
A calculate the kVA rating for a single-phase transformer, you will need to multiply the required input voltage (V) by the required current load in amperes (l) and then divide that number by 1,000: V * l / 1,000.
kVAh is short for "kilovolt-ampere hour." It is a measure of perceived power, which comprises both reactive and actual power.
