base is base

Fill in the fields (except the third field which is read-only).
When you hit the tab key the third field will be recalculated.

I didn't write this converter — my math skills are far too inadequate for that! As far as I remember the author was  someone on the Conlang email list.  I just changed it to use base 12, as in Quenya, as default value and put it up here on my site, so that everyone can use it — including me when away from home!
