This calculator is to find out input current of induction motor. You can find amperes of both single phase and three phase equipments when kW is known to you.
KW to Ampere Calculator
How to use the calculator?
- From the drop down, select the phase.
- For this calculator, note down the voltage, efficiency, power factor and kW of the motor. You can find details from the motor nameplate.
- Enter the data collected in respective fields.
- You can take value 0.8 for pf and 0.8 for efficiency if it is not available on motor name plate.
- The calculator would show automatically the calculated value.
Formulas to Convert kW to Amperes
Single Phase formula to Convert kW to Amperes
For single phase, amperes (A) is equal to kilowatts (kW) multiply by 1000 whole divided by Voltage (V) multiply by Power Factor (PF) multiply by Efficiency (EFF). Multiplying by thousand would convert kilowatts into watts.
Three Phase formula to Convert kW to Amperes
For three phase, amperes (A) is equal to kilowatts (kW) multiply by 1000 whole divided by Voltage (V) multiply by Power Factor (PF) multiply by Efficiency (EFF) multiply by square root of 3.
