## How to convert electric current in amps (A) to apparent power in kilovolt-amps (kVA)?

### amps(A) to kVA calculation formula in Single phase

**S(kVA) = I(in amps) × V(in Volts) / 1000**

So that you can define kilovolt-amps are equivalent to amps(A) times volts(V) divided by 1000.

**kilovolt-amps = amps(A) × volts(V) / 1000**

**or**

**kVA = A x V / 1000**

**Let’s take one example**

**Example#1**

Find out the apparent power in kVA(S) where the phase current(I) is 10A and the RMS(root mean square) voltage supply is 120V in the circuit.

Apply formula for the solution:

S = 10A × 120V / 1000 = 12kVA

### Online amps to kVA calculation formula in 3 phase (Calculation with line to line voltage)

**S(kVA) = √3 × I(in Amps) × VL-L(in Volts) / 1000**

So that you can define kilovolt-amps(Kva) are equal to 1.732 times amps(A) times volts(V) divided by 1000.

**kilovolt-amps = 1.732 × amps(A) × volts(V) / 1000**

**or**

**kVA = 1.732 × A x V / 1000**

**Let’s take one example**

**Example#2**

Calculate the apparent power(S) in kVA where the phase current(I) is 10A and the line to line RMS(root mean square) voltage(V) supply is 120V in the circuit.

Apply formula for the solution:

S = 1.732 × 10A × 120V / 1000 = 2.07kVA

### Online amps to kVA calculation formula in 3 phase (Calculation with line to neutral voltage)

**S(kVA) = 3 × I(in Amps) × VL-N(in Volts) / 1000**

So that you can define kilovolt-amps(Kva) are equivalent to 3 times amps(A) times volts(V) divided by 1000.

**kilovolt-amps = 3 × amps(A) × volts(V) / 1000**

**or**

**kVA = 3 × A x V / 1000**

**Let’s take one example**

**Example#3**

Find out the apparent power(S) in kVA where the phase current(I) is 10A and the line to neutral RMS(Root Mean Square) voltage(V) supply is 110V in the circuit.

Apply formula for the solution:

S = 3 × 10A × 110V / 1000 = 3.3kVA
