Conversion using the Amps to KW Formula

DC Amps to KW Calculation formula

The Real Power P in Kilowatts Kw is calculated as the current I in amps A, times the voltage in volts V divided by 1000. Plug these values into the formula:

Real Power(P) = Current(I) × Voltage(V) 1000

or, P(KW) = I(A) × V(V) 1000

or, KW = Amps × Volts 1000

For Example, let's find the power in kilowatts for a circuit with 8 amps of current at 100 volts.

Single Phase Amps to KW Calculation formula

The Real Power P in Kilowatts kw is calculated as the Power factor in pf times the phase current I in amps A, times the RMS voltage in volts v divided by 1000. Plug these values into the formula:

Real Power(P) = Power factor(pf) × Current(I) × Voltage(V) 1000

or, P(KW) = pf × I(A) × V(V) 1000

or, KW = pf × Amps × Volts 1000

For Example, If the Voltage consumption is 240V with a phase current of 8A and a power factor of 0.8 the Real Power is KW.

3-Phase Amps to KW Calculation formula

Calculation with Line to Line voltage

The Real Power P in Kilowatts Kw is as the square root of 3 times the Power factor in Pf times the phase current I amps A, times the Line-to-Line RMS Voltage V_L-L in Volts v divided by 1000. Plug these values into the formula:

Real Power(P) = 3 × Power factor(pf) × Current(I) × Voltage(line-line) 1000

or, P(KW) = 3 × pf × I(A) × V(line-line) 1000

or, KW = 3 × pf × Amps × Volts 1000

For Example, If the RMS Line-line 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.

Calculation with Line to Neutal voltage

The Real Power P in Kilowatts Kw is as the 3 times the Power factor in Pf times the phase current I amps A, times the Line-to-neutral RMS Voltage V_L-N in Volts v divided by 1000. Plug these values into the formula:

Real Power(P) = 3 × Power factor(pf) × Current(I) × Voltage(line-Neutral) 1000

or, P(KW) = 3 × pf × I(A) × V(line-Neutral) 1000

or, KW = 3 × pf × Amps × Volts 1000

For Example, If the RMS Line-Neutral Voltage consumption is 440V with a 3-phase the phase current is 10A, and a Power factor of 0.8 the Real Power is KW.

Frequently Asked Questions - FAQs for Amps to KW Calculator

What is 0 voltage?

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

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.

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.

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 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.
