### Formulas used for Watts to Amps conversion calculator.

The formula used for the watts-to-amps conversion depends on the electrical system’s voltage and power factor. Here are the formulas for different scenarios:

**For DC Circuits:**

- In a DC circuit, the formula to calculate current (I) from power (P) and voltage (V) is:

**I = P
V**

**For AC Single Phase (with Power Factor):**

**I = P
V x PF**

**AC Three Phase (Line to Line Voltage):**

**I = P
√3 x V x PF**

**AC Three Phase (Line to Neutral Voltage):**

**I = P
3 x V x PF**

**For AC Circuits (without Power Factor):**

- If the power factor is not provided, the formula assumes a power factor of 1 (unity power factor). In this case, the formula to calculate current (I) from power (P) and voltage (V) is the same as for DC circuits:

**I = P
V**
