Conversion Using the Power Formula :

DC Amps to KW Calculation:

The Real power (P) in kilowatts (kW) is equal to the current I in amps (A), times the voltage V in volts (V) divided by 1000:

For example, let’s find the power in kilowatts for a circuit with 8 amps of current at 80 volts.

P(KW) = I(A) x V(V) ÷ 1000
P(KW) = 8 x 80 ÷ 1000
P(Kw) = 0.640

AC Single Phase Amps to Kw Calculation:

The Real 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 1000:

For example, If the Voltage consumption is 220V with a phase current of 5A and a power factor of 0.8  the Real Power is KW.

P(KW) = Pf x I(A) x V(V) ÷ 1000
P(KW) = 0.8 x 5 x 220 ÷ 1000
P(Kw) = 0.88 Kw

Ac Three Phase Amps to KW Calculation :

Calculation with Line to Line Voltage:

The Real Power (P) in kilowatts (kW) is equal to the 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:

For example, If the RMS Line-line Voltage consumption is 440V with a 3-phase the phase current is 2A, and a Power factor of  0.8 the Real Power is KW.

P(KW) = √3 x Pf x I(A) x V(V) ÷ 1000
P(KW) = √3 x 0.8 x 2 x 440 ÷ 1000
P(Kw) = 1.219 Kw

Calculation with Line to Neutral Voltage:

The Real 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:

For example, If the RMS Line-Neutral Voltage consumption is 440V with a 3-phase the phase current is 5A, and a Power factor of  0.8 the Real Power is KW.
P(KW) = √3 x Pf x I(A) x V(V) ÷ 1000
P(KW) = √3 x 0.8 x 5 x 440 ÷ 1000
P(Kw) = 5.280 Kw

Where:

    • P = Power in Kilowatts (KW)
    • V = Voltage in volts
    • I = Current in amperes
    • Cosθ = Power factor in AC circuits
    • VL-L = Line to Line Voltage in 3-Phase Circuits
    • VL-N = Line to Neutral Voltage in 3-Phase Circuits

Frequently asked questions

How do I convert amps (A) to Kilowatts (kW)?

A convert amps to kilowatts, the modified formula shows us that the power (kilowatts) is equal to the current (A) multiplied by the voltage (V), which is then divided by 1,000.

What are amps in watts?

How to Convert Watts, Amps, & Volts
Watts = Amps x Volts
Examples: 30 Amps x 220 Volts = 6600 Watts. 10 Amps x 240 Volts = 2400 Watts.

What is 0 voltage?

0v, or zero volts, a complete lack of voltage. Zero-voltage switching; see Switched-mode power supply.

Is low voltage 0 or 1?

Typically, we assign the logic value “1” to the higher output voltage and “0” to the lower output voltage termites. Circuits built with real components actually operate with continuous voltages and current flow.

How much current is 1 amp?

1 ampere of current represents 1 coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in 1 second.
