The number represents roughly the degrees longitude covered by the map. However
it is a continuous variable unlike the arithmatic progression you use for map
scales. I do not see a reason to limit my users to a handful of map scales when
the system is capable of much more.

As to matching the units to yours, this is not something people will be
communicating to each other, a user will find the number that produces the map
he likes, and create a link using that value, so there is no benefit to changing
it.
