Explanation
watt-hours and joules are units of energy. They are used in common measurement contexts. Which one you use depends on the unit system or industry. They are defined at different scales, so the factor is not 1: 1 watt-hours = 3600 joules, and 1 joules = 0.0002777778 watt-hours. Because one joules represents a smaller amount than one watt-hours, the numeric value gets larger in this direction.
How to convert watt-hours to joules
- Enter the value in watt-hours (Wh).
- Multiply it by 3600.
- The result is the equivalent value in joules (J).
- Round the result if needed.
Worked example
