Amps :

  • Ampere (A) is the SI base unit of electric current.

Watts :

  • Watt (W) measures electrical power consumption.

Formulas :

  • DC: W = A × V
  • Single Phase: W = PF × A × V
  • Three Phase (L-L): W = √3 × PF × A × V
  • Three Phase (L-N): W = 3 × PF × A × V

How to Calculate ?

  • Select the current type.
  • Enter current and voltage.
  • Enter power factor for AC.
  • Click “Calculate” to get watts.
