How to Convert Kilowatts (kW) to Amps
Converting kW to amps is simple once you know your system’s voltage, phase type, and power factor. Below is a quick breakdown to help you understand the process clearly.
kW to Amps Formula (Single-Phase)
Amps = (kW × 1000) ÷ (Volts × Power Factor)
kW to Amps Formula (Three-Phase)
Amps = (kW × 1000) ÷ (√3 × Volts × Power Factor)
√3 = 1.732
These formulas work by converting power (kW) to VA, then dividing by voltage and power factor to find current.
Step-by-Step Conversion Example
Example for Single-Phase
- kW = 5
- Voltage = 230V
- Power Factor = 0.8
Amps = (5 × 1000) ÷ (230 × 0.8) = 27.17A
Example for Three-Phase
- kW = 15
- Voltage = 400V
- Power Factor = 0.9
Amps = (15 × 1000) ÷ (1.732 × 400 × 0.9) = 24.03A
