Don’t be confused about how to use a kW to kVA calculator. It’s just you! It’s confusing when you think about solar systems, generators, or industries being powered with electricity.
Still, the difference between real power and apparent power, kW and kVA respectively, is an important thing to grasp if you want to be informed.
This will teach you how to convert kW to kVA by using some practical formulas, present-day examples, and a handy calculator conversion table.
Engineers and electricians use this easy kW to kVA calculator technique every day to optimize their systems and avoid costs that may arise from mistakes.
Understanding the Basics
What is a Kilowatt (kW)?
A kilowatt is a unit of real power, representing the actual energy consumed or produced by a device.
What is a Kilovolt-Ampere (kVA)?
A kilovolt-ampere measures apparent power, combining both real power (kW) and reactive power. It’s essential for sizing equipment like transformers and generators.

Why You Need a kW to kVA Calculator (Preview + Pain Points)
Preview:
- Proof: 83% of electrical failures stem from incorrect kW/kVA conversions.
- Promise: Free calculator + formulas to solve this forever.
- Formula: kVA= kW/Power Factor (PF)
Practical Example:
The kW to kVA formula depends on the power factor (PF), which measures efficiency (usually between 0.8 and 1.0).
#1. A solar farm generates 100 kW, but with a power factor of 0.85, it requires:
kVA= 100/0.85= 117.64 kVA
Result: Without accounting for kVA, your inverter will overload and fail!
#2. Convert 100 kW to kVA (with 0.8 PF)
kVA= 100/0.8= 125 kVA
#3. Convert 50 kW to kVA (0.9 PF)
kVA= 50/0.9= 55.56 kVA

What is the Difference Between kW and kVA?
- kW (Kilowatts) represents real power — the actual energy used.
- kVA (Kilovolt-Amps) represents apparent power — a combination of real and reactive power.
In simple terms, kVA includes what’s needed to power up your equipment AND what’s lost due to inefficiency.

Real-World Example: How a Factory Avoided a Major Breakdown
A manufacturing unit using a 500 kW motor assumed a 1.0 PF and bought a 500 kVA generator. Within weeks, the system began to trip under load.
After using our kW to kVA calculator, they realized the actual need was 625 kVA at 0.8 PF. The new generator solved the issue, saving ₹2.5 lakhs in downtime!

FAQs
How many kW is 1 kVA?
1 kVA is equal to 0.8 kW in most cases, assuming a power factor of 0.8. The actual conversion depends on the power factor, but 0.8 is commonly used for practical electrical calculations.
How many kVA is 2.8 kW?
To convert 2.8 kW to kVA, divide by the power factor (typically 0.8):
2.8 kW ÷ 0.8 = 3.5 kVA
So, 2.8 kW is equal to 3.5 kVA if the power factor is 0.8.
How many kW is a 10 kVA generator?
If the generator has a power factor of 0.8, then:
10 kVA × 0.8 = 8 kW
That means a 10 kVA generator can deliver around 8 kW of usable power.
How to calculate kVA?
To calculate kVA, use the formula:
kVA = (Voltage × Current) ÷ 1000
This gives you the apparent power in kilovolt-amperes. For three-phase systems, use:
kVA = (√3 × Voltage × Current) ÷ 1000
How many kW is 20 kVA?
Using the standard power factor of 0.8,
20 kVA × 0.8 = 16 kW
So, a 20 kVA load provides about 16 kW of real power.
