How to Convert kvar to Microfarad
Converting kVAR to microfarads is common when sizing capacitors for power factor correction. The formula relates reactive power to the capacitive reactance of the component.
Formula:
Where:
- C = Capacitance in microfarads (µF)
- kVAR = Reactive power
- f = Frequency in Hz
- V = Voltage in volts
Step-by-Step Example
Example: Convert 10 kVAR to microfarads at 400V and 50Hz
Step 1: Write the formula
C = (kVAR × 109) / (2 × π × f × V²)
Step 2: Substitute values
C = (10 × 109) / (2 × 3.1416 × 50 × 400²)
Step 3: Calculate voltage square
400² = 160,000
Step 4: Multiply constants
2 × 3.1416 × 50 = 314.16
Step 5: Final calculation
C = (10,000,000,000) / (314.16 × 160,000)
Step 6: Solve
C ≈ 199 µF
Result: 10 kVAR ≈ 199 microfarads at 400V, 50Hz

Unit Standardization: SI vs. Imperial Sizing in kvar to Microfarad
When working with kvar to Microfarad 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 Microfarad to ensure they match equipment specification sheets.
