Amps to kW Calculator

Amperes to Kilowatt Conversion Calculator

Select current type:  
Enter current in amps: A
Enter voltage in volts: V
   
Power result in kilowatts: kW
It is a conversion calculator which changes the current in Amps (A) and the voltage in volts (V) to power results in Kilowatts (kW). The first step is to select the current type. It can either be Direct Current denoted as (DC) or alternating current (AC). The next text field gives you an option of entering the current in Amps while the other requires you to fill in the voltage in volts.

The procedure is simple, and you can tap the Calculate button which performs the calculation in a single click. The Reset button erases everything in the text fields and can be used when you want to carry out other calculations.

For example, if you have 100 Amps and 80 Volt with a Direct current, then your power result in Kilowatts will be 8 kW. If the current type was AC- Single Phase, you can enter 100 Amps and 80 Volts in the required cells.

You can then enter the power factor which should range from 0 to 1. e.g. 0.567. Clicking on the Calculate button will give you the power result in Kilowatts as 4.536 kW. The AC-three Phase is wider and will require you to choose the voltage type. The options are the line to line voltage and line to neutral voltage.

If you have 100 Amps, 80 Volts, 0.567 power factor with line to line being your energy type, then the power in results in Kilowatts will be 7.8565824631 (kW).

There are ways in which the calculator executes the calculations;

Estimate of DC amps to Kilowatts
P (kW) = I (A) x V (V) /1000, which means that the power in Kilowatts is calculated by multiplying the current in Amps with the voltage in volts and divide the results by 1000.

Calculation of AC Single Phase to (kW)
P (kW) = PF x I (A) x V (V) / 1000, which means that the power in Kilowatts is calculated by multiplying the power factor by the phase current in Amps times the voltage RMS in Volts dividing the results by 1000.

Calculation of AC three Phase amps to Kilowatts
Line to line Voltage
P (kW) = √3 x PF x I (A) x V L-L (V) / 1000, which means that the power in Kilowatts is calculated by the square root of three multiplied by the power factor times the phase current in amps by the line to line voltage RMS. The results are then divided by 1000.

Line to neutral Voltage
P (kW) = 3 x PF x I (A) x V L-N (V) / 1000, which means that the power in Kilowatts is calculated by multiplying three by the power factor times the Phase current in amps by the line to neutral voltage RMS dividing the results by 1000.
