How to convert kilowatts to amps

How to convert electric power in kilowatts (kW) to electric current in amps (A).

You can calculate amps from kilowatts and volts. You can't convert kilowatts to amps since kilowatts and amps units do not measure the same quantity.

DC kilowatts to amps calculation formula

The formula for converting power in kilowatts to current in amps is:

I(A) = 1000 × P(kW) / V(V)

So amps are equal to 1000 times kilowatts divided by volts.

amps = 1000 × kilowatts / volts

where

I is the current in amps,

P is the power in kilowatts,

V is the voltage in volts.

To use the formula, simply substitute the values for P and V into the equation and solve for I.

For example, if you have a power consumption of 0.66 kilowatts and a voltage supply of 110 volts, you can calculate the current in amps like this:

I = 1000 × 0.66kW / 110V = 6A

This means that the current in the circuit is 6 amps.

It's important to note that this formula assumes that the power factor is equal to 1. If the power factor is not equal to 1, you'll need to include it in the calculation by multiplying the power in kilowatts by the power factor. For example, if the power factor is 0.8, the formula would become:

I = 1000 × (0.8 × P(kW)) / V(V)

This would give you the correct current value for the circuit.

AC single phase kilowatts to amps calculation formula

The formula for converting real power in kilowatts to phase current in amps for an AC circuit is:

I = 1000 × P / (PF × V )

where

I is the phase current in amps,

P is the real power in kilowatts,

PF is the power factor,

V is the RMS voltage in volts.

To use the formula, simply substitute the values for P, PF, and V into the equation and solve for I.

For example, if you have a power consumption of 0.66 kilowatts, a power factor of 0.8, and an RMS voltage supply of 110 volts, you can calculate the phase current in amps like this:

I = 1000 × 0.66kW / (0.8 × 110V) = 7.5A

This means that the phase current in the circuit is 7.5 amps.

It's important to note that this formula assumes that the power factor is a decimal value between 0 and 1. If the power factor is not a decimal value between 0 and 1, you'll need to convert it to a decimal value first before using the formula. You can do this by dividing the power factor by 100. For example, if the power factor is 80%, the decimal value would be 0.8.

AC three phase kilowatts to amps calculation formula

The formula for converting real power in kilowatts to phase current in amps for a three-phase AC circuit is:

I = 1000 × P / (√3 × PF × VL-L )

where

I is the phase current in amps,

P is the real power in kilowatts,

PF is the power factor,

VL-L is the line-to-line RMS voltage in volts.

To use the formula, simply substitute the values for P, PF, and VL-L into the equation and solve for I.

For example, if you have a power consumption of 0.66 kilowatts, a power factor of 0.8, and a line-to-line RMS voltage supply of 110 volts, you can calculate the phase current in amps like this:

I = 1000 × 0.66kW / (√3 × 0.8 × 110V) = 4.330A

This means that the phase current in the circuit is 4.330 amps.

It's important to note that this formula assumes that the power factor is a decimal value between 0 and 1. If the power factor is not a decimal value between 0 and 1, you'll need to convert it to a decimal value first before using the formula. You can do this by dividing the power factor by 100. For example, if the power factor is 80%, the decimal value would be 0.8.
