Kilowatts to kVA calculator
Convert real power in kilowatts (kW) to apparent power in kilovolt-amperes (kVA). Ideal for understanding the total power requirements of electrical systems and equipment. Obtain an estimation of kilovolt-amperes from kilowatts using this convenient online tool.
What is Kilowatts to kVA calculator
To convert kilowatts (kW) to kilovolt-amps (kVA), you need to know the power factor (PF) of the load. The formula for converting kilowatts to kilovolt-amps is:
kVA = kW / PF
Simply divide the power in kilowatts by the power factor to obtain the apparent power in kilovolt-amps.
For example, if you have a load with a power consumption of 6 kW and a power factor of 0.8, you can calculate the apparent power in kilovolt-amps as follows:
kVA = 6 kW / 0.8 kVA = 7.5 kVA
In this example, the load has an apparent power of 7.5 kilovolt-amps.
Please note that kilovolt-amps (kVA) represent the apparent power of an electrical system, which includes both real power (measured in kilowatts) and reactive power. The power factor (PF) represents the ratio of real power to apparent power and indicates how effectively electrical power is being utilized. For loads with unknown or unspecified power factors, it is common to assume a power factor of 1 (unity) for simplicity or refer to specific device or system specifications for accurate power factor values.
kW to kVA calculation
The apparent power S in kilovolt-amps (kVA) is equal to the real power P in kilowatts (kW), divided by the power factor PF:
S(kVA) = P(kW) / PF
Kilowatts to kVA calculator Example
To convert kilowatts (kW) to kilovolt-amps (kVA), you need to know the power factor (PF) of the electrical system. The formula to calculate kVA from kW and power factor is:
kVA = kW / PF
Here's an example that demonstrates the calculation:
Let's assume you have a power factor of 0.8 and a power consumption of 10 kW.
kVA = 10 kW / 0.8 = 12.5 kVA
Therefore, the apparent power in kilovolt-amps corresponding to a power consumption of 10 kW with a power factor of 0.8 would be 12.5 kVA.
It's important to note that kilovolt-amps (kVA) represents the apparent power in an electrical system, taking into account both the real power (kW) and the reactive power. The power factor is crucial in determining the kVA rating, as it indicates the efficiency or quality of the electrical system.
