Full precision:2.7778e-22 Wh
Step-by-Step Solution
To convert 1e-18 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:
1e-18 ÷ 3600 = 2.7778e-22 watt-hours
So 1e-18 joules = 2.7778e-22 watt-hours.
Quick check: 2.7778e-22 × 3600 = 1e-18 joules
