Conversion using the Amps to KVA Formula

How to Calculate KVA from amps and volts using AC Single Phase current.

The apparent power in kilovolt-amps is equal to the current in amps, times the voltage in volts, divided by 1000:

KVA = Amps × Volts1000

For Example, single-phase system with 240 volts and 50 amps, the apparent power is ____ kVA.

Apparent Power(S) = Current(I) × Voltage(V)1000

or, S(KVA) = 50 amps × 240 volts1000

or, apparent power = 12 KVA

How to Calculate KVA from amps and volts using AC 3-phase current for Line-to-Line Voltage.

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line-to-line RMS voltage V _L-L in volts, divided by 1000:

KVA = 3 × Amps × Volts1000

For Example, 3-phase system with a line-to-line voltage of 400 volts and 50 amps, the apparent power is approximately ____ kVA

Apparent Power(S) = 3 × Current(I) × Voltage(V)1000

or, S(KVA) = 3 × 400 amps × 50 volts1000

or, apparent power = 34.64 KVA

How to Calculate KVA from amps and volts using AC 3-phase current for Line-to-Neutral Voltage.

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to neutral RMS voltage V_L-N in volts, divided by 1000:

KVA = 3 × Amps × Volts1000

For Example, 3-phase system with a line-to-neutral voltage of 440 volts and 50 amps, the apparent power is approximately ___ kVA.

Apparent Power(S) = 3 × Current(I) × Voltage(V)1000

or, S(KVA) = 3 × 50 amps × 440 volts1000

or, apparent power = 66 KVA

Frequently Asked Questions - FAQs for Amps to KVA Calculator

What is amps to kVA?

To calculate kVA from Amps, multiply the amperage by the voltage in volts, then divide the result by 1000.

What is 300 amps in kVA?

300 Amps at 12 Volts would be 3600 VA or 3.6 kVA.

What is kVA to kW?

The formula for converting kVA into kW is:
For example, a 400kVA generator with a power factor of 0.8 outputs 160kW actual power; 400 kVA x 0.8 = 320 kW.

What are 30 amps in watts?

How to Calculate Electrical Load Capacity for Safe Usage 30-amp 220-volt circuit: 30 amps x 220 volts = 6,600 watts or 6.6Kw.
