Full precision:0.27778 Wh
Step-by-Step Solution
To convert 1000 joules to watt-hours, we divide by 3600 because one watt-hour equals exactly 3600 joules.
1 watt-hour = 3600 joules
Since there are 3600 joules in every watt-hour, we divide our value by this factor:
1000 ÷ 3600 = 0.27778 watt-hours
So 1000 joules = 0.27778 watt-hours.
Quick check: 0.27778 × 3600 = 1000 joules
