Learn KW to KVA conversion with simple formulas, examples, and a conversion table. Easily convert kilowatts to KVA using our step-by-step guide and calculator.
When dealing with electrical power, it is crucial to understand the relationship between kilowatts (KW) and kilovolt-amperes (KVA). Many professionals and students often search for KW to KVA conversion to determine apparent power in an electrical system. This guide will provide a simple explanation of KW to KVA calculation, the formula, examples, and how you can easily convert KW to KVA using a calculator.
What is kW and kVA?
Kilowatts (kW)
KW represents real power in an electrical circuit. It is the actual power consumed by the electrical devices and converted into useful work.
Kilovolt-Amperes (kVA)
KVA is the apparent power, which includes both real power (KW) and reactive power. It accounts for the total power supplied to an electrical system.
Power Factor (PF)
Power factor (PF) is the ratio of real power to apparent power and determines how effectively electrical power is used. It ranges from 0 to 1, with 1 being the most efficient.
kW to kVA Conversion Formula
To convert kilowatts to KVA, the following formula is used:

Where:
- KVA = Apparent Power
- KW = Real Power
- PF = Power Factor (typically 0.8 for industrial loads)
kW to kVA Conversion Table
KW | Power Factor PF (0.8) | KVA= KW/PF |
---|---|---|
1 | 0.8 | 1.25 |
5 | 0.8 | 6.25 |
10 | 0.8 | 12.5 |
50 | 0.8 | 62.5 |
100 | 0.8 | 125 |
kW to kVA Calculator
If you want a quick and accurate KW to KVA calculator, simply use the formula:

For example:
If 1 KW needs to be converted to KVA at 0.8 PF, then:
1kW= 1/0.8= 1.25 kVA
How to Convert kW to kVA?
- Identify the kW value of the device or system.
- Determine the power factor
- Apply the kW to kVA conversion formula.( kVA= kW/PF)
- Calculate the result.
Examples of kW to kVA Conversion
Example 1: Convert 10 KW to KVA
- Given: KW = 10, PF = 0.8
- Formula: KVA=kw/PF=10/0.8=1.25 kVA
Example 2: Convert 5 KW to KVA
- Given: KW = 5, PF = 0.9
- Formula: KVA=kw/PF=5/0.9= 5.56 kVA
Common kW to kVA Conversions at 0.8 PF
- 1KW to KVA = 1.25 KVA
- 10 KW to KVA = 12.5 KVA
- 100 KW to KVA = 125 KVA
Conclusion
Understanding KW to KVA conversion is essential for electrical engineers, students, and professionals in power management. Whether using a manual formula or a KW to KVA calculator, knowing how to convert KW to KVA ensures accurate power calculations in electrical systems.
For quick calculations, always remember: kVA= kW/PF
