Elec Training: Amps to Watts

Calculate electrical power from current and voltage with the Elec Training Amps to Watts calculator.

Choose DC, single-phase AC or three-phase AC, enter your values and view the result in watts and kilowatts, with the formula and step-by-step working.

SUPPORTED CALCULATIONS
• DC: P = I × V
• Single-phase AC: P = I × V × PF
• Balanced three-phase AC: P = √3 × I × V × PF

For three-phase calculations, enter line current and line-to-line voltage.

FEATURES
• Results in watts and kilowatts
• Power factor input for AC calculations
• Common voltage presets
• Formula, substituted values and calculation steps
• Plain-English explanations
• Works offline
• Free, with no ads or account required

Designed for electrical students, apprentices and anyone revising electrical power calculations.

For learning and revision only. This calculator must not replace competent electrical design, BS 7671 or professional judgement.
