## DC amps to kilowatts calculation

So The power P in kilowatts (kW) is equal to the current  I in amps (A), times the voltage  V in volts (V) divided by .

P(kW) = I(A) × V(V) / 1000

#### Example 1

What is power consumption in kW when the current is 5A and the voltage supply is 110V?

Answer: the power P is equal to current of 5 amps times the voltage of 110 volts, divided by 1000.

P = 5A × 110V / 1000 = 0.55kW

#### Example 2

What is power consumption in kW when the current is 12A and the voltage supply is 110V?

Answer: the power P is equal to current of 12 amps times the voltage of 110 volts, divided by 1000.

P = 12A × 110V / 1000 = 1.32kW

#### Example 3

What is power consumption in kW when the current is 13A and the voltage supply is 190V?

Answer: the power P is equal to current of 13 amps times the voltage of 190 volts, divided by 1000.

P = 13A × 190V / 1000 = 2.47kW

## AC single phase amps to kilowatts calculation

So The power P in kilowatts (kW) is equal to the power factor  PF times the phase current  I in amps (A), times the RMS voltage  V in volts (V) divided by .

P(kW) = PF × I(A) × V(V) / 1000

#### Example 1

What is power consumption in kW when the power factor is 0.8 and the phase current is 12A and the RMS voltage supply is 110V?

Answer: the power P is equal to power factor of 0.8 times current of 12 amps times voltage of 110 volts, divided by 1000.

P = 0.8 × 12A × 110V / 1000 = 1.056kW

#### Example 2

What is power consumption in kW when the power factor is 0.8 and the phase current is 15A and the RMS voltage supply is 110V?

Answer: the power P is equal to power factor of 0.8 times current of 15 amps times voltage of 110 volts, divided by 1000.

P = 0.8 × 15A × 110V / 1000 = 1.32kW

#### Example 3

What is power consumption in kW when the power factor is 0.8 and the phase current is 25A and the RMS voltage supply is 110V?

Answer: the power P is equal to power factor of 0.8 times current of 25 amps times voltage of 110 volts, divided by 1000.

P = 0.8 × 25A × 110V / 1000 = 2.2kW

## AC three phase amps to kilowatts calculation

#### Calculation with line to line voltage

The power  P in kilowatts (kW) is equal to square root of 3 times the power factor  PF times the phase current  I in amps (A), times the line to line RMS voltage  VL-L in volts (V) divided by 1000:

P(kW) = 3 × PF × I(A) × VL-L (V) / 1000

#### Example 1

What is power consumption in kW when the power factor is 0.8 and the phase current is 5A and the RMS voltage supply is 110V?

Answer: the power P is equal to square root of 3 times power factor of 0.8 times current of 5 amps times the voltage of 110 volts, divided by 1000.

P = 3 × 0.8 × 5A × 110V / 1000 = 0.762kW

#### Example 2

What is power consumption in kW when the power factor is 0.8 and the phase current is 12A and the RMS voltage supply is 110V?

Answer: the power P is equal to square root of 3 times power factor of 0.8 times current of 12 amps times the voltage of 110 volts, divided by 1000.

P = 3 × 0.8 × 12A × 110V / 1000 = 1.829kW

#### Calculation with line to neutral voltage

The power  P in kilowatts (kW) is equal to 3 times the power factor  PF times the phase current  I in amps (A), times the line to neutral RMS voltage  VL-N in volts (V) divided by 1000:

P(kW) = 3 × PF × I(A) × VL-N (V) / 1000
