Conversion using the Amps to VA Formula

Single Phase Amps to VA Calculation formula

The Apparent Power S in Volt-amps is calculated as the Current I in amps A, times the voltage in volts v. Plug these values into the formula:

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

or, S(VA) = I(A) × V(V)

or, VA = Amps × Volts

For Example, let's find the volt-amps for a single-phase circuit with 15 amps of current at 220 volts.

3-Phase Amps to VA Calculation formula

Calculation with Line to Line voltage

The Apparent Power S in Volt-amps VA us calculated as the square root of 3 times current I in Amps A, times the line-to-line Voltage V_L-L in Volts V. Plug these values into the formula:

Apparent Power(S) = 3 × Current(I) × Voltageline-line (volt)

or, S(VA) = 3 × I(A) × VL-L (volt)

or, VA = 3 × Amps × Volts

For Example, let's find the amps for a 440 volt 3-phase electrical circuit with 90 amps of current.

Calculation with Line to Neutral voltage

The Apparent Power S in Volt-amps VA us calculated as the 3 times current I in Amps A, times the line-to-neutral Voltage V_L-N in Volts V. Plug these values into the formula:

Apparent Power (S) = 3 × Current (I) × Voltageline-Neutral (volt)

or, S(VA) = 3 × I (A) × VL-N (volt)

or, VA = 3 × Amps × Volts

For Example, let's find the amps for a 480 volt 3-phase electrical circuit with 70 amps of current.

Frequently Asked Questions - FAQs for Amps to VA Calculator

Is it VA or kVA?

A KVA is simply 1000 volt-amps. A volt is an electrical pressure. An amp is an electrical current. A term called apparent power (VA) is equal to the product of the volts and amps.

What is 4000 VA?

Alternating Current) 4000 Volt Amps, is 4000 Watts for a purely resistive load. However, the current flow will be out of phase with respect to the voltage for an inductive (some motors) or capacitive (buried cables) load.

What is a watt formula?

Watts = Amps x Volts
20 Amps x 120 Volts = 2400 Watts.
10 Amps x 230 Volts = 2300 Watts.

How to convert HP to kVA?

Now 1HP = 1492W=1.492kW=1.492kVA , assuming power Factor=1.

What is VA in amps?

A volt-ampere (VA) is a measurement of Real power in a direct current (DC) electrical circuit. The VA specification is also used in alternating current (AC) circuits.
