How do I convert kVA to amps using this calculator?

Select your phase type (single-phase or three-phase), choose the correct voltage type for three-phase (line-to-line or line-to-neutral), enter the kVA value and voltage, and the calculator will instantly display the current in amps using the correct formula.

Which formulas does the kVA to Amps Calculator use?

For single-phase systems, it uses I(A) = (kVA × 1000) / V. For three-phase line-to-line systems, it uses I(A) = (kVA × 1000) / (√3 × VLL). For three-phase line-to-neutral systems, it uses I(A) = (kVA × 1000) / (3 × VLN).

Does this calculator account for power factor?

This tool assumes a power factor of 1 and focuses on apparent power (kVA) only. For real-world electrical design, protection, and sizing, you should factor in the actual power factor and consult an electrician or engineer.

Is kvatoamps.com free to use on any device?

Yes. kvatoamps.com is completely free and optimized for desktop, tablet, and mobile devices, so you can quickly run kVA to amps conversions wherever you are.

How the kVA to Amps Calculator Works

Select Single phase or Three phase.
For three phase, choose Line-to-Line (V_LL) or Line-to-Neutral (V_LN).
Enter the apparent power in kVA and the voltage in volts.
Click Calculate to get current in amps with the correct formula.
Adjust Precision for more or fewer decimal places.

How to convert kVA to amps (single-phase)?

Use I(A) = (kVA × 1000) / V. Example: 5 kVA at 230 V → (5 × 1000) / 230 ≈ 21.74 A.

How to convert kVA to amps (3 phase, line-to-line)?

Use I(A) = (kVA × 1000) / (√3 × V_LL). Example: 10 kVA at 400 V → (10 × 1000) / (1.732 × 400) ≈ 14.43 A.

How to convert kVA to amps (3 phase, line-to-neutral)?

Use I(A) = (kVA × 1000) / (3 × V_LN). Example: 10 kVA at 230 V line-to-neutral → (10 × 1000) / (3 × 230) ≈ 14.49 A.

What affects kVA to amps conversion?

The result depends on voltage level, phase type, and whether you are using line-to-line or line-to-neutral voltage. This tool assumes a power factor of 1 for simplicity (apparent power only).
