Summary
This tool calculates the unknown in the fundamental physics relationship P = W / t — finding work (energy), power, or time from the other two values. Definitions: - Work (W): Energy transferred by a force over a distance. Unit: Joule (J). - Power (P): Rate of doing work per unit time. Unit: Watt (W). - Time (t): Duration over which work is performed. Unit: second (s). Core formulas: - P = W / t (power) - W = P · t (work) - t = W / P (time) SI units: - W (work / energy): Joule [J] - P (power): Watt [W] - t (time): second [s] Note: For large energy values, the result is also shown in kWh.
