Power Calculator for Generators: Convert kVA to kW Calculator
Real power (in kW) is equal to the power factor of the load (PF) multiplied by the phase current measured in Amps (A), times the RMS voltage (V), and divided by 1000.

Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.
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) = 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) = 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:
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
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.
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.
0v, or zero volts, a complete lack of voltage. Zero-voltage switching; see Switched-mode power supply.
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.
1 ampere of current represents 1 coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in 1 second.
