Example of Watts to Watt-Hours Calculations

To convert watts (W) to watt-hours (Wh), you need to know the duration of power usage in hours. The formula to convert watts to watt-hours is:

Watt-Hours = Watts × Hours

For these calculations, we’ll assume common watt values and varying durations.

Table of Watts to Watt-Hours Conversions

Below is a table showing the conversion of various watt values to watt-hours, assuming different durations of power usage (in hours).
