Watt-hours to Joules Converter
How to convert watt-hours to joules
joules = watt-hours × 3,600
To convert watt-hours to joules, multiply the number of watt-hours by 3,600.
1 Wh = 3,600 J
Examples
- The usual airline limit for a lithium battery in carry-on baggage: 100 Wh × 3,600 = 360,000 J
- 1,000 Wh × 3,600 = 3,600,000 J

Unit definitions
- Watt-hour (Wh)
- A watt-hour is the energy used by a 1 watt load running for one hour, exactly 3600 joules. It is used for battery capacities.
- Joule (J)
- The joule is the SI unit of energy, equal to the work done by a force of one newton over one meter, or one watt for one second.
