To calculate amps per kilowatt, multiply the kilowatts by 1000, then divide by the product of the power factor (PF) and voltage (V).
The Amps Per kW Calculator is suitable for converting electrical power in kilowatts (kW) to current in amperes (A). This is essential for electrical engineers, electricians, and anyone working with power systems to size circuits, determine load capacities, and ensure system efficiency.
Whether you’re working with single-phase or three-phase power, this calculator simplifies complex calculations, offering accurate results for residential, commercial, or industrial electrical setups.
Formula
A = (1000 × kW) / (PF × V)
| Variable | Description |
|---|---|
| A | Current in Amps |
| kW | Power in Kilowatts |
| PF | Power Factor (unitless, typically 0 to 1) |
| V | Voltage (in Volts) |
Solved Calculations
Example 1 (Single-Phase):
| Input | Value |
|---|---|
| Power (kW) | 5 kW |
| Voltage (V) | 230 V |
| Power Factor (PF) | 0.9 |
| Formula Used | A = (1000 × 5) / (0.9 × 230) |
| Current (A) | ~24.15 A |
Example 2 (Three-Phase):
| Input | Value |
|---|---|
| Power (kW) | 15 kW |
| Voltage (V) | 400 V |
| Power Factor (PF) | 0.8 |
| Formula Used | A = (1000 × 15) / (0.8 × 400 × √3) |
| Current (A) | ~27.04 A |
