Orders of magnitude (energy)

This list compares various energies in joules (J), organized by order of magnitude.

Below 1 J

1 to 10⁵ J

10⁶ to 10¹¹ J

10¹² to 10¹⁷ J

10¹⁸ to 10²³ J

Over 10²³ J

SI multiples

The joule is named after James Prescott Joule. As with every SI unit named for a person, its symbol starts with an upper case letter (J), but when written in full, it follows the rules for capitalisation of a common noun; i.e., joule becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case.
