Electrical Power calculator

Calculate power (Watt)

  • Potential: 5 V (Volt)
  • Current: 5 A (Ampere)
  • Active power: 25 W (Watt)
  • Calculate energy (KWh/Joule)

  • After 1 hours of continuous power usage:
  • Current: 5 Ah
  • kWh: 25 Wh
  • Joule: 90 MJ
  • Calorie: 21.5 Mcal
  • Compare

    Compare 25 W to standard power from:
    DC (Direct Current)AC (Alternating Current)
