Amps to Watts Calculator
Power in watts is simply the current in amps multiplied by the voltage, and this calculator handles that for you. For a DC circuit or a resistive AC load, watts equal amps times volts. For a real AC load with a power factor below one, such as a motor or fluorescent lighting, the true power is amps times volts times the power factor, so the tool provides a power factor field. Converting current to power is useful for reading how much a device costs to run, for staying within the wattage limit of a generator or inverter, and for balancing loads across a supply. As an example, a five amp draw on a 120 volt outlet is 600 watts of power. Enter the current, the voltage, and a power factor if your load is inductive, then read the power instantly. Everything runs locally in your browser, so it is fast and private.
How to use Amps to Watts Calculator
- Enter the current in amps.
- Enter the circuit voltage.
- Add a power factor for AC loads, or use 1 for DC.
- Read the power in watts.
Frequently asked questions
How does it convert amps to watts?
For DC it multiplies current by voltage, and for single phase AC it also multiplies by the power factor, since watts equal volts times amps times power factor.
When should I include a power factor?
Include it for AC motors and reactive loads where current and voltage are out of phase; a resistive load or DC circuit uses a power factor of 1.
Is the result real power or apparent power?
With a power factor below 1 the watts figure is real power, the useful power delivered, which is less than the apparent volt-amps.
What is Amps to Watts Calculator?
