Electric Work

Compute electrical energy from W = U I t and convert to joules, watt-hours and kilowatt-hours.

Inputs

Formula

W = U I t

How to use

  1. Fill in Voltage U, Current I, Time t in the Inputs section (watch the unit on each field).
  2. Click Calculate; the tool evaluates the formula shown above.
  3. Read Energy W, Watt-hour Wh, kWh in the results area.
Formula notesElectric work W = U·I·t = P·t (U voltage, I current, t time, P power).
