Kilowatt to Ampere Converter
Calculate current (A) from power (kW) and voltage for both AC and DC circuits.
How to Convert Kilowatts to Amperes
To convert kilowatts (kW) to amperes (A), the formula depends on the electrical system type: DC, Single-phase AC, or Three-phase AC.
Kilowatts to Amperes Formula
To calculate current (I) in amperes based on power (P) in kilowatts and voltage (V) in volts, you can use the following formula:
Quick Trick: To find the current, multiply the kilowatts by 1000 and divide by the voltage!
Conversion Formulas
DC Circuit Calculation
P(kW) = I(A) × V(V) / 1000
Where:
- P = Power in Kilowatts
- I = Current in Amps
- V = Voltage in Volts
AC Single Phase Calculation
P(kW) = PF × I(A) × V(V) / 1000
Where:
- PF = Power Factor
- I = Current in Amps
- V = RMS Voltage in Volts
AC Three Phase Calculation
Line to Line:
P(kW) = √3 × PF × I(A) × VL-L(V) / 1000
Line to Neutral:
P(kW) = 3 × PF × I(A) × VL-N(V) / 1000
Understand the Conversion
The relationship between power, current, and voltage is defined by the formula:
- If you know the power (P) in kilowatts and voltage (V), you can calculate the current (I) using: I = P × 1000 / V
Simply input the known values and use the formula to calculate the current in amperes.
Kilowatt (kW) - A Unit of Power
Kilowatts are a standard unit of power, used to measure electrical power. One kilowatt is equal to 1,000 watts, which indicates the rate at which electricity is generated or consumed.
Ampere (A) - A Unit of Current
Amperes (or amps) are a standard unit of electric current, measuring the flow of electric charge. One ampere is defined as the flow of one coulomb of charge per second.
