Welcome to **4.5 kW to amps**, which stands for 4.5 kilowatts to amperes.

If you have been wondering *how many amps is 4.5 kW*, then you have come to the right post, too.

To obtain 4.5 kW in amps in case of direct current (DC), we only have to know the potential difference in volts (V).

To be able to transform 4.5 kilowatt to ampere with alternating current (AC), we additionally must know the power factor, the number of phases and perhaps the voltage type.

## Convert 4.5 kW to Amps

To convert 4.5 kW to amps, thereby changing the power (P) to current (I), consider the criteria below. Next apply the corresponding 4.5 kilowatts (kW) to amps (A) formula further down.

For the conversion of 4.5 kW to amp check whether your electric current is of type direct or alternating flow of electric charge, as explained in details on our article Watts to Amps.

For alternating currents, the 4.5 kW amp transformation is different for a single phase and a 3 phase system; the power factor is needed in both cases.

In case of the three-phase electrical generation, line to line voltage and line to neutral voltage require different constants to convert 4.5 kilowatts to amps, (√3) and 3, respectively.

- DC: I
_{(A)}= 1000 × 4.5 kW / V_{(V)} - AC, Single Phase: I
_{(A)}= 1000 × 4.5 kW / (PF × V_{(V)}) - AC, Three Phase, Line to Line Voltage: I
_{(A)}= 1000 × 4.5 kW / (√3 × PF × V_{L-L(V)}) - AC, Three Phase, Line to Neutral Voltage: I
_{(A)}= 1000 × 4.5 kW / (3 × PF × V_{L-0(V)})

In an alternating current circuit, the power factor (PF) is the quotient of real power / apparent power with a value in between 0 and 1: 0 ≤ PF ≤ 1; real power here is = 4.5 kW.

The next section exemplifies a number of 4.5 kW to amps calculations.

Next, we will answer *what is the current in amperes if the power consumption is 4.5 kW and the voltage supply is 110 V*?

## 4.5 kW to Amps Conversion

From our formulas follows that in order to get 4.5 kilowatts in amps we must know the voltage. Assumed the PF is 0.5, and supposed the voltage is 110 V, we get these result:

- DC: I = 1000 × 4.5 kW / 110 V = 40.91 A
- AC, Single Phase: I = 1000 × 4.5 kW / (0.5 × 110 V) = 81.82 A
- AC, Three Phase, Line to Line Voltage: I = 1000 × 4.5 kW / (√3 × 0.5 × 110 V) = 47.24 A
- AC, Three Phase, Line to Neutral Voltage: I = 1000 × 4.5 kW / (3 × 0.5 × 110 V) = 27.27 A

Instead of applying the formulas use our kW to amps converter. Insert, for example, 4.5 for the power in kilowatts; your voltage in volts is also required for all conversions.

Depending on your selected current and the number of phases, the power factor as well as the voltage type may also have to be entered to transform 4.5 kW to amp.
