# Watts to Amps Calculator

Watt is the unit of power, represented using the symbol 'W'. It is a standard unit of power and energy. Ampere is the SI unit of electric current represented as 'A'. It is a unit of electric current equal to a flow of one coulomb per second. The watt unit is named after James Watt, the inventor of the steam engine and ampere is named after AndrÃ©-Marie AmpÃ¨re, a French mathematician and physicist. Here is an online Watts to Amps Calculator to convert W to A.

#### Formula:

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

#### Example

A DC current of 5 Watts has 10 voltage. What is its equivalent ampere?
Amp = 5 /10
= 0.5 A

You can convert watts to amps for DC, AC-single phase and AC-three phase using this online watts to ampere converter.
