How to Convert kVAR to Amps - Step by Step Guide
To convert kvar to amps, use these formulas:
Single-Phase Formula
Three-Phase Formula
Step-by-Step Example (Three-Phase)
Given:
- Reactive Power = 50 kVAR
- Voltage = 400 V
Step 1: Use formula
I = (kVAR × 1000) / (√3 × V)
Step 2: Substitute values
I = (50 × 1000) / (1.732 × 400)
Step 3: Solve
I = 50000 / 692.8
I ≈ 72.2 Amps
Final Answer: The current is approximately 72.2 A.

| 50 | 217.4 A | 72.2 A |
| 75 | 326.1 A | 108.3 A |
| 100 | 434.8 A | 144.3 A |
| 150 | 652.2 A | 216.5 A |
| 200 | 869.6 A | 288.7 A |
Unit Standardization: SI vs. Imperial Sizing in kVAR to Amps
When working with kVAR to Amps 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 Amps to ensure they match equipment specification sheets.
