kW to kVA Calculator
Easily convert kilowatts (kW) to kilovolt-amperes (kVA) with our accurate calculator. Supports single-phase and three-phase systems.
Quick Intro: Convert kW to kVA
Convert kilowatts (kW) to kilovolt-amperes (kVA) instantly using our accurate and easy-to-use calculator. The conversion is based on the power factor (PF), which reflects the efficiency of electrical usage. This tool supports both single-phase and three-phase electrical systems, allowing you to input the real power and power factor to obtain the apparent power. Perfect for electrical engineers, energy consultants, and technical students, this calculator simplifies your electrical design and planning needs.
Formula to Convert kW to kVA
Use the following formulas to convert kW to kVA:
kVA = kW / PFThree Phase:
kVA = kW / (√3 × PF)- kW = Real Power
- kVA = Apparent Power
- PF = Power Factor (0 to 1)
kW to kVA Calculator Overview
The kW to kVA calculator is a useful tool for converting real power (kilowatts) into apparent power (kilovolt-amperes). The conversion depends on the power factor, which typically ranges between 0 and 1. This tool supports both single-phase and three-phase systems, making it ideal for engineers, electricians, and students. Understanding this conversion is crucial for designing and evaluating electrical systems, especially in industrial and commercial settings. Whether you're estimating generator capacity or planning energy loads, this calculator helps ensure accurate and efficient power management.

| kW | Power Factor | Single Phase kVA | Three Phase kVA |
|---|---|---|---|
| 10 | 0.8 | 12.5 | 7.21 |
| 25 | 0.8 | 31.25 | 18.03 |
| 50 | 0.8 | 62.5 | 36.08 |
Frequently Asked Questions - kW to kVA Calculator:
What is the formula to convert kW to kVA?
kVA = kW / Power Factor (PF).
What is Power Factor?
Power Factor is the ratio of real power (kW) to apparent power (kVA).
What is the difference between kW and kVA?
kW is real power; kVA is apparent power including reactive power.
Is kVA higher than kW?
Yes, kVA is usually higher due to power factor losses.
What is a good power factor?
A power factor of 0.9 or above is considered good.
How to calculate kVA for a 3-phase system?
kVA = kW / (√3 × PF).
Why do we use kVA instead of kW for generators?
Generators are rated in kVA because they supply both real and reactive power.
Can power factor be greater than 1?
No, power factor ranges from 0 to 1.
What happens if power factor is low?
Low power factor results in higher apparent power and inefficiency.
Is this calculator accurate for all voltages?
Yes, if the power factor and phase type are correctly applied.
