Kilovolt-amps to amps calculator: convert apparent power into current

A kilovolt-amps to amps calculator converts apparent power into current for single-phase or balanced three-phase AC systems when you know the supply voltage. It is useful for turning kVA-based equipment ratings into line current, comparing single-phase and three-phase current demand, and checking how an apparent-power nameplate maps to the current the system must carry.

What this kilovolt-amps to amps calculator solves

This page converts apparent power in kilovolt-amps into current using the selected AC system and the entered voltage. Single-phase mode divides apparent power by voltage directly, while balanced three-phase mode uses the square-root-of-three factor tied to line-voltage relationships.

That makes the calculator a good fit when the published rating starts in kVA rather than in amps and you need the resulting current for comparison or early planning.

The current formulas behind the result

In single-phase AC, current equals kVA multiplied by 1,000 and divided by voltage. In balanced three-phase AC, the calculator divides by the square-root-of-three multiplied by line voltage. The result panel also shows the supporting volt-amp figure so the apparent-power scale remains easy to audit.

The exact working equation is displayed beside the result, which makes it easy to verify the calculation and confirm that the chosen phase mode matches the supply you are modeling.

A = (kVA x 1,000) / V

Use for single-phase AC when apparent power and supply voltage are known.

A = (kVA x 1,000) / (√3 x V)

Use for balanced three-phase AC when line voltage and apparent power are known.

VA = kVA x 1,000

Shows the same apparent power at the volt-amp scale.

How to interpret the current result

The current result is the line current implied by the entered apparent power and voltage assumptions. That is useful for equipment comparisons, early supply checks, and turning a kVA-based nameplate into the current it implies on the selected system type.

Because the headline stays in amps, the page keeps the promised output unit explicit instead of auto-scaling it into another current prefix. The supporting VA figure still helps keep the apparent-power side traceable.

What this simplified conversion does not replace

This calculator does not perform conductor sizing, breaker selection, motor-start analysis, or code-compliance checks. It also does not model imbalance, harmonics, or changing operating conditions.

Use it as an educational and planning conversion tool. For installation or procurement decisions, verify the result against the actual nameplate, measured operating conditions, and the applicable electrical code or engineering standard.

Frequently asked questions

Why do I need voltage if the nameplate already shows kVA?

Because current depends on both apparent power and supply voltage. The same kVA rating produces different current values at different voltages.

 What voltage should I use for three-phase calculations?

Use the line voltage that matches the balanced three-phase formula on this page. The calculator applies the √3 factor internally.

 Can I use this result to size wiring or breakers directly?

No. It only solves the current implied by the entered apparent power and voltage. Final protection and conductor sizing still require separate code-based checks.
