# Amps to Watts Calculator

Ampere (amps or amperage) is an SI unit of electric current and is denoted by 'A'. 1 Ampere is defined as the electrical current that flows with electric charge of one Coulomb per second. Watt is an SI unit of electric power and is denoted by 'W'. 1 watt is defined as the energy consumption rate of one joule per second. Here is a useful online Amps to Watts Calculator which helps you in converting electrical unit Ampere (A) To Watt (W) (Amperage to Wattage).

#### Formula:

**DC amps to watts**
Watt = Ampere x Volt
**AC single phase amps to watts**
Watt = Ampere x Volt x Power factor
**AC three phase amps to watts (With line to line voltage)**
Watt = √3 x Ampere x Line to line RMS voltage x Power factor
**AC three phase amps to watts (With line to neutral voltage)**
Watt = 3 x Ampere x Line to neutral RMS voltage x Power factor

#### Example

**A single phase AC current of 12 Amps has voltage of 5 and power factor of 0.2. What is the equivalent wattage?**

= 12 x 5 x0.2

= 12 W.

Ampere to watt conversion for direct and alternating current is made easier in this amps to watts calculator. Watt is also defined as the flow of electrical current of one ampere with one volt. 1W = 1J / 1s.
