Formula for Amps to MVA
For accurate conversion, use the correct formula:
Step-by-Step Example (Three-Phase)
Convert 400 amps at 11,000 volts to MVA.
Step 1: Write the formula
MVA = (√3 × V × I) ÷ 1,000,000
Step 2: Insert values
MVA = (1.732 × 11,000 × 400) ÷ 1,000,000
Step 3: Multiply values
MVA = (1.732 × 4,400,000) ÷ 1,000,000
Step 4: Final result
MVA = 7.62 MVA
Key Notes
- Use √3 only for three-phase systems.
- Divide by 1,000,000 to convert VA to MVA.
- This calculation applies to apparent power.

Quick Reference Table (220V Single-Phase / 400V Three-Phase)
| Amps (A) | 1-Phase (220V) | 3-Phase (400V) |
|---|---|---|
| 50 A | 0.01 MVA | 0.03 MVA |
| 100 A | 0.02 MVA | 0.07 MVA |
| 200 A | 0.04 MVA | 0.14 MVA |
| 300 A | 0.07 MVA | 0.21 MVA |
| 400 A | 0.09 MVA | 0.28 MVA |
| 500 A | 0.11 MVA | 0.35 MVA |
| 600 A | 0.13 MVA | 0.42 MVA |
| 800 A | 0.18 MVA | 0.55 MVA |
| 1000 A | 0.22 MVA | 0.69 MVA |
Unit Standardization: SI vs. Imperial Sizing in Amps to MVA
When working with Amps to MVA 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 Amps to MVA to ensure they match equipment specification sheets.
