## DC kW to volts calculation formula

V_{(V)} = 1000 × P_{(kW)} / I_{(A)}

The voltage **V** in volts (V) is equal to 1000, multiplied by the power **P** in kilowatts (kW), divided by the current **I** in amps (A).

So,

*V = 1000 x kW / A*

*volt = 1000 x kilowatt / amp*

**For example:**

*Power (P) = 5kW*

*Phase current (I) = 2,5A*

*Voltage (V) = 1000 x 5kW / 2,5A = 2000V*

## AC single phase kW to volts calculation formula

V_{(V)} = 1000 × P_{(kW)} / (PF × I_{(A)})

The voltage **V** in volts (V) is equal to 1000, multiplied by the power **P** in kilowatts (kW), divided by the power factor **PF**, multiplied by the current **I** in amps (A).

So,

*V = 1000 x kW / (PF x A)*

*volt = 1000 x kilowatt / (PF x amp)*

**For example:**

*Power (P) = 5kW*

*Phase current (I) = 2,5A*

*PF = 0,5*

*Voltage (V) = 1000 x 5kW / (0,5 x 2,5A) = 4000V*

## AC three phase kW to volts calculation formula

V_{L-L(V)} = 1000 × P_{(kW)} / (√3 × PF × I_{(A)})

The line to line RMS voltage **V**_{L-L} in volts (V) is equal to 1000, multiplied by the power **P** in kilowatts (kW), divided by square root of 3, multiplied by the power factor **PF**, multiplied by the current **I** in amps (A).

So,

*V = 1000 x kW / (√3 × PF x A)*

*volt = 1000 x kilowatt / (√3 × PF x amp)*

**For example:**

*Power (P) = 5kW*

*Phase current (I) = 2,5A*

*PF = 0,5*

*Voltage (V) = 1000 x 5kW / (√3 × 0,5 x 2,5A) = 2309,401V*
