Conversion using the Amps to KVA Formula

Single Phase Amps to KVA Calculation formula

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

Apparent Power(S) = Current(I) × Voltage(V) 1000
or, S(KVA) = I(A) × V(V) 1000
or, KVA = Amps × Volts 1000

For Example,

3-Phase Amps to KVA Calculation formula

Calculation with 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:

Apparent Power(S) = 3 × Current(I) × Voltage(V) 1000
or, S(KVA) = 3 × I(A) × Vline-line 1000
or, KVA = 3 × Amps × Volts 1000

For Example,

Calculation with Line to Neutal voltage

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

Apparent Power(S) = 3 × Current(I) × Voltage(V) 1000
or, S(KVA) = 3 × I(A) × Vline-Neutral 1000
or, KVA = 3 × Amps × Volts 1000

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.
