## Watts to Amps Formula

The following equation can be used to convert watts to amps.

For DC Currents: I = P / V

- Where I is the current (amps)
- P is the power in Watts
- V is the voltage in volts

For AC Currents: I = P/ (V*PF)

- Where I is the current (amps)
- P is the power in watts
- V is the voltage in volts
- PF is the power factor.

When solving for DC currents, leave the power factor section blank. The power factor is a measure of the efficiency of AC currents since they are represented by a single-phase sine wave. As can be seen, by the equations above, converting watts to amps is not a direct conversion. This is because watts are a measure of energy per unit time and amps are a measure of current. These are different values and as a result, you need additional information, in this case, the voltage, to convert one value to the other.
