How to convert watt-hours to joules

Multiply the value in Wh by 3,600: the result is in J.

J = Wh × 3,600The other way round, 1 J = 0.000277777778 Wh.

Where these two units are used

The watt-hour measures battery capacity, and it is what airlines read: above 100 watt-hours, a lithium battery boards the cabin only with prior approval. The joule is one newton-meter and bears the name of James Joule, whose 1845 experiment showed that a falling weight and a burning flame do the same thing. Lifting one tonne by one meter costs 9,810 joules, that is 2.7 watt-hours: a loaded lift climbing ten floors spends roughly what a laptop draws in an hour.
