Watt Hours Calculation

Introduction: The Watt Hours Calculator is a convenient tool for calculating energy consumption. This article introduces the calculator, guiding users on its functionality and benefits.

Formula: The formula for calculating Watt-Hours is straightforward: Energy (Wh)=Power (Watts)×Time (Hours)Energy (Wh)=Power (Watts)×Time (Hours)

How to Use:

  1. Input the power consumption in Watts.
  2. Enter the time duration in hours.
  3. Click the “Calculate” button to obtain the total energy consumption in Watt-Hours.

Example: For example, if a device consumes 50 Watts of power for 2 hours, the calculated energy consumption would be 100 Watt-Hours.
