Volts to kW calculator

Volts to Kilowatts Calculator

It is used to convert the electrical voltage in volts (V) to the electric power in Kilowatts (kW). It is simple to use, and the accuracy depends on the values entered in the cells. Start by selecting the current type before filling in the voltage in volts and current in amps. Click on the ‘Calculate' button to give you the power result in Kilowatts. The ‘Calculate' and ‘Reset' buttons have been programmed to perform their intended functions with a single click.

Calculating the Direct Current (DC) volts to kilowatts

P (kW) = V (V) x I (A) / 1000, which means that the power in kilowatts is computed by multiplying the voltage in volts by the current in amps. The result is then divided by 1000.

For example;

If the current in amps is 10 A and the voltage supply is 25V, what is the power consumption in kilowatts?

Solution

P (kW) = V (V) x I (A) / 1000

= 25 V x 10 A / 1000 = 0.25 Kilowatts (kW)

Calculating the Alternating current (AC) single phase volts to Kilowatts

P (kW) = PF x I (A) x V (V) / 1000, which means that the power in Kilowatts is computed by multiplying the power factor by the current in amps times the voltage RMS in volts. The result is then divided by 1000.

For example;

If the single phase current is 5A and the power factor is 0.9. What is the power consumption in Kilowatts if it has a voltage supply of 145 V?

Solution

P (kW) = PF x I (A) x V (V) / 1000

= 0.9 x 5A x 145 V / 1000 = 0.6525 Kilowatts (kW)

Calculating the AC three phase volts to Kilowatts

P (kW) = √3 x PF x I (A) x V L-L (V) / 1000, which means that the real power in Kilowatts is calculated by the square root of three multiplied by the power factor by the phase current in amps times the voltage RMS in volts. The result is then divided by 1000.
