Kilowatts to VA calculator
Convert real power in kilowatts (kW) to apparent power in volt-amperes (VA). Perfect for understanding the total power requirements of electrical systems and equipment. Obtain an estimation of volt-amperes from kilowatts using this convenient online tool.
What is Kilowatts to VA calculator
To convert kilowatts (kW) to volt-amps (VA), you need to know the power factor (PF) of the load. The formula for converting kilowatts to volt-amps is:
VA = kW / PF
Simply divide the power in kilowatts by the power factor to obtain the apparent power in volt-amps.
For example, if you have a load with a power consumption of 8 kW and a power factor of 0.9, you can calculate the apparent power in volt-amps as follows:
VA = 8 kW / 0.9 VA ≈ 8.89 kVA
In this example, the load has an approximate apparent power of 8.89 kilovolt-amps.
Please note that volt-amps (VA) represent apparent power, which is the combination of real power 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 VA calculation
The apparent power S in volt-amps (VA) is equal to 1000 times the real power P in kilowatts (kW), divided by the power factor PF:
S(VA) = 1000 × P(kW) / PF
Kilowatts to VA calculator Example
To convert kilowatts (kW) to volt-amps (VA), you need to know the power factor (PF) of the electrical system. The formula to calculate VA from kW and power factor is:
VA = kW / PF
Here's an example that demonstrates the calculation:
Let's assume you have a power factor of 0.9 and a power consumption of 5 kW.
VA = 5 kW / 0.9 ≈ 5.56 kVA or 5560 VA
Therefore, the apparent power in volt-amps corresponding to a power consumption of 5 kW with a power factor of 0.9 would be approximately 5.56 kVA or 5560 VA.
Please note that apparent power (VA) represents the total power in an electrical system, combining both real and reactive power. The power factor should always be considered when converting between kilowatts and volt-amps, as it affects the actual power delivered to the load.
