Volts :
  • The volt is the derived unit for electric potential, electric potential difference, and electromotive force.It is named after the Italian physicist Alessandro Volta.
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⋅s⁻³ or, equivalently, 1 joule per second.It is used to quantify the rate of energy transfer.
Volts to Watts :
  • It is used to convert the voltage in volts (V) to the power in watts (W) using the current in amps (A).Start by selecting the type of current which can either be the direct current (DC) or Alternating current (AC) single phase/ three phase.
DC to Volts :
  • P (W) = V (V) x I (A).
  • Which means that the power in watts is computed by multiplication of the voltage in volts by the current in amps.
AC Single Phase from Volts to Watts :
  • P (W) = PF x I (A) x V (V).
  • Which means that the real power in watts is computed by multiplying the phase current in amps by the voltage RMS in volts.
AC Three Phase from Volts to Watts :
  • P (W) = √3 x PF x I (A) x V L-L (V).
  • Which means that the real power in watts is calculated by multiplying the square root of three by the power factor times the phase current in amps.
  • The result is then multiplied by the voltage RMS in volts.
