Energy conversion factors [closed]

edit

@Kastro1501 please adhere to our question tagging conventions so you don't clutter them with meaningless ones.

1. use existing tags whenever possible instead of creating new ones.
2. use a - to separate words in a single tag instead of using a tag for each word
3. don't use general or vague tags such as energy or os

Please retag, thanks!

Also, did you use the search before posting? I found this previous question.
