This list compares various energies in joules (J), organized by order of magnitude.
This is the strongest chemical bond known.
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.
