Convert amps to kilowatts on a 12 volt supply. This assumes a resistive load with a power factor of 1, so for motors and other AC loads divide the power by the power factor as well.
Worked example
Example calculated from the starting values. Enter your own values and press Calculate to get your result.
With the default inputs (current = 10 A), the results are: power at 12 V 0.120 kW.
Quick reference: current vs result
Reference table based on the example values; it is not your calculation result.
| Current (A) | Power at 12 V |
|---|---|
| 5 | 0.060 kW |
| 10 | 0.120 kW |
| 20 | 0.240 kW |
| 50 | 0.600 kW |
| 100 | 1.200 kW |

Frequently asked questions
What formula does this calculator use?
Power at 12 V = x × volts ÷ 1000. Variables: x = current in A. Fixed values: volts = 12.
What do I need to enter?
You need current (A). Results update as you type.
What is an example result?
With the default inputs (current = 10 A), the results are: power at 12 V 0.120 kW.
