Watts to Amps :

Electrical Calculator
Select current type:
Enter power in watts: W
Enter voltage in volts: V
Current result in amps: A
Watts :
  • The watt is a unit of power or radiant flux.In the International System of Units, it is defined as a derived unit of 1 kg·m²·s³ or, equivalently, 1 joule per second.
  • It is used to quantify the rate of energy transfer.
Amps :
  • The ampere, often shortened to amp, is the SI base unit of electric current.One ampere is equal to 6.241509074×10¹⁸ electrons worth of charge moving past a point in a second.
Watts to Amps :
  • It is used to convert the electric power in watts (W) to the current in amps (A).
DC Watts to Amps :
  • I (A) = P (W) / V (V).
  • Where the current in amps is computed by dividing the power in watts by the voltage in volts.
AC Single Phase Watts to Amps :
  • I (A) = P (W) / (PF x V (V).
  • Where the phase current in amps is calculated by dividing the real power in watts by the power factor multiplied by voltage in volts.
AC Three Phase Watts to Amps ,
Line to Line Voltage :
  • I (A) = P (W) / (√3 x PF x V L-L (V)).
  • Which means that the phase current in amps is computed by dividing the real power in watts by the multiplication of square root of three, time the power factor.
  • Then the result is multiplied by the line to line voltage RMS in volts.
Line to Neutral Voltage :
  • I (A) = P (W) / (3 x PF x V L-N (V)).
  • Which means that the phase current in amps is computed by dividing the real power in watts by the multiplication of three by the power factor multiplied by the line to neutral voltage in volts.
