kVA to kW Calculator
Convert apparent power in kilovolt-amperes (kVA) to real power in kilowatts (kW). Ideal for understanding the actual power consumption of electrical systems and equipment. Obtain an estimation of kilowatts from kVA using this practical online tool.
What is kVA to kW Calculator
To convert kilovolt-amps (kVA) to kilowatts (kW), you need to know the power factor (PF) of the load. The formula for converting kVA to kW is:
kW = kVA x Power Factor (PF)
Simply multiply the apparent power (kVA) by the power factor (PF) to obtain the real power in kilowatts.
For example, if you have a load with an apparent power of 8 kVA and a power factor of 0.9, you can calculate the real power consumption in kilowatts as follows:
kW = 8 kVA x 0.9 kW = 7.2 kW
In this example, the load consumes 7.2 kilowatts of real power.
The power factor (PF) represents the ratio of real power to apparent power. It 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.
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:
P(kW) = S(kVA) × PF
kVA to kW Calculator Example
To convert kilovolt-amps (kVA) to kilowatts (kW), you need to know the power factor (PF) of the electrical system. The formula to calculate kilowatts from kVA and power factor is:
kW = kVA * PF
Here's an example that demonstrates the calculation:
Let's assume you have a power factor of 0.8 and a kVA rating of 10 kVA.
kW = 10 kVA * 0.8 = 8 kW
Therefore, the power in kilowatts corresponding to a 10 kVA rating with a power factor of 0.8 would be 8 kilowatts.
Please note that the power factor represents the efficiency or quality of the electrical system. The power factor should always be considered when converting between kVA and kW, as it affects the actual power delivered to the load.
