To convert amps to kilowatts, multiply the amps by the voltage. For example, if you have an 8.33 amp appliance running on a 120V circuit, the power draw would be 8.33 amps x 120V = 1 kW.
When working with the calculations of the conversions you have to make sure that the set of units is consistent in order to get correct answers. When it comes to how much power will be consumed by certain appliances and lighting fixtures the most commonly used terms are Amps and Watts. There is a huge difference between the two though as watts could be a comprehensive measure of power whereas amps are simply the amount of current being drawn.
Amps (Ampere): It is important to be able to quantify the amount of current flowing in a circuit as it enables the performance of the circuit to be defined and for the circuit to operate as required. To achieve this, it is necessary to have a unit which is ampere or amp.
KW (Kilowatts): KW is known as actual power or working power. Kilowatts is the amount of power that is converted into a useful output. Power could be a measure of how rapidly one thing is generating or generating energy. In many ways, the average KW values are easier to work with.
Alternating Current (AC): Alternating current is the flow of charge. As a result, the voltage level additionally reverses together with this.AC is used to deliver power to homes, office buildings, etc. AC can be produced by an alternator.
Direct Current (DC): Direct current could be a bit easier to understand than AC. Rather than periodical back and forth, DC provides a constant voltage or current. An AC generator equipped with a device called Commutator can produce direct current.
It is a conversion calculator that changes the current in Amps (A) and the voltage in Volts (V) to power in Kilowatts (KW). The first step is to select the current type. It can either be direct current (DC) or alternating current (AC). The next step is to enter the current is amps and after that, the next field gives you an option to enter voltage in volts. Then simply you have to tap on calculate button and it will perform the calculation in a single click. The reset button erases everything in the text fields and can be used for further calculations.
Conversions of amps to kw according to current types:
1. DC amps to kilowatts calculation
P(kW) = I(A) × V(V) / 1000 The P (power) in kW (kilowatts) is equal to the I (current) in A (amps), times the V (voltage) in V (volts) divided by 1000.
2. AC single phase amps to kilowatts calculation
P(kW) = PF × I(A) × V(V) /1000 The P (power) in Kilowatts is a product of the PF (power factor), I (current) in (amps), and RMS V (voltage) in (volts) divided by 1000.
3. AC three phase amps to kilowatts calculation
Calculation with line-to-line voltage
P(kW) = √3 × PF × I(A) × VL-L (V) / 1000 The P (power) in kW (kilowatts) is equal to the square root of 3 times the PF (power factor) times the phase I (current)in A (amps), times the line-to-line RMS voltage VL-L in V (volts) divided by 1000
Calculation with a line to neutral voltage
P(kW) = 3 × PF × I(A) × VL-N (V)/1000 The P (power) in (kilowatts) is a product of three times the PF (power factor) times the phase I (current), times neutral RMS voltage VL-N divided by 1000 VL-N in V (volts) divided by 1000.
