How to Convert kVAR to kWh
You cannot directly convert kVAR to kWh because they measure different quantities: kVAR (reactive power) and kWh (energy). You must include power factor and time.
Formula
Step-by-Step Example
Let’s calculate energy using a real example:
Given:
- Reactive Power = 50 kVAR
- Power Factor = 0.8
- Time = 10 hours
Step 1: Multiply kVAR by Power Factor
50 × 0.8 = 40 kW (real power)
Step 2: Multiply by Time
40 × 10 = 400 kWh
Final Answer: Energy = 400 kWh

Assumptions: Power Factor = 0.8, Time = 1 hour
| Reactive Power (kVAR) | Time (Hours) | Energy (kWh) |
|---|---|---|
| 5 kVAR | 1 h | 4 kWh |
| 10 kVAR | 1 h | 8 kWh |
| 20 kVAR | 1 h | 16 kWh |
| 30 kVAR | 1 h | 24 kWh |
| 50 kVAR | 1 h | 40 kWh |
| 75 kVAR | 1 h | 60 kWh |
| 100 kVAR | 1 h | 80 kWh |
| 150 kVAR | 1 h | 120 kWh |
| 200 kVAR | 1 h | 160 kWh |
Note: Multiply values by hours for longer durations.
Unit Standardization: SI vs. Imperial Sizing in kVAR to kWh
When working with kVAR to kWh calculations, using consistent physical units is vital. Small translation errors between SI Metric units (like millimeters, kilowatts, and meters) and Imperial units (like AWG wire, horsepower, and feet) can lead to serious sizing errors:
| Dimension | SI Metric Unit | Imperial Unit | Conversion Conversion Factor |
|---|---|---|---|
| Power | Kilowatts (kW) | Horsepower (HP) | 1 kW ≈ 1.341 HP |
| Length | Meters (m) | Feet (ft) | 1 m ≈ 3.2808 ft |
| Flow Rate | Cubic meters/hr (m³/h) | Gallons/minute (GPM) | 1 m³/h ≈ 4.403 GPM |
Always perform unit checks before installing physical components for kVAR to kWh to ensure they match equipment specification sheets.
