Direct current (DC) and alternating current (AC) flows can both be converted from amps to watts with the help of this calculator.

**DC amps to watts Conversion:**

Power, measured in watts (W), is euqual to the sum of current, measured in amps (A), and voltage, measured in volts (V):

**P = I × V**

**AC amps to watts Conversion:**

### Watts to Amps conversion for ac voltage with a single phase:

The power, measured in watts (W), is equal to the power factor, PF, multiplied by the phase current, measured in amps (A), and multiplied by the RMS voltage, measured in volts (V).

**P = PF × I × V**

### Watts to Amps conversion for ac voltage with a three phase(L-L Volt):

The power, measured in watts (W), is calculated as the square root of three times the power factor, PF, multiplied by the phase current, measured in amps (A), and multiplied by the line-to-line RMS voltage, measured in volts (V):

**P = √3 × PF × I × V _{L-L}**

### Watts to Amps conversion for ac voltage with a three phase(L-N Volt):

The power, measured in watts (W), is equal to three times the power factor, PF, multiplied by the phase current, measured in amps (A), and multiplied by the line-to-neutral RMS voltage, V_{L-N}, in volts (V):

**P = 3 × PF × I × V _{L-N}**
