Watts :

  • Watt (W) is the SI unit of electrical power.
  • It measures the rate of energy transfer.

Amps :

  • Ampere (A) is the SI base unit of electric current.
  • It represents the flow of electric charge.

Watts to Amps :

  • Used to convert electrical power (W) into current (A).
  • Calculation depends on DC, AC single-phase, or AC three-phase.

Formulas :

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

How to Calculate ?

  • Select the current type.
  • Enter watts and voltage.
  • Provide power factor if applicable.
  • Click “Calculate” to get amps.
