Watts to Watt Hours

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).

Convert 100 Watts to Watt-Hours

To convert 100 watts used over 2 hours to watt-hours:

Watt-Hours = 100 × 2 = 200 Wh

Convert 500 Watts to Watt-Hours

To convert 500 watts used over 4 hours to watt-hours:

Watt-Hours = 500 × 4 = 2000 Wh

Convert 1000 Watts to Watt-Hours

To convert 1000 watts used over 5 hours to watt-hours:

Watt-Hours = 1000 × 5 = 5000 Wh
