In this dialogue you can set up up to five different conversion tables. Only pure multiplications are supported, that is, you can only convert ratios (y = ax).
You can give each tabbed page a name (“Group”), and populate it with up to ten different names/values. The values are used to divide/multiply numbers; you could for example enter “cm” with a value of 1, and “inch” with a value of 2.54. That’s all there is to it.
Note: To ease keyboard operations in the conversion dialogue, you may want to stick an ampersand (&) in front of a character in the group name. For example, if you name a group “&Speed”, you will automatically add the keyboard shortcut Alt-S to the conversion dialogue.
The items will always be allocated shortcuts Alt-0—Alt-9 and Alt-A—Alt-J, so you may want to avoid using these, as well as Alt-U, Alt-M, Alt-N, Alt-R, Alt-V or Alt-T, which are reserved for the fixed groups and the Edit button. (True, it doesn’t leave you very much…)
