I don't have any problem adding more units. If you or somebody wants to prepare a list I'll be happy to add them.
They could also become an external "Prime unit pack", and define for instance the "inch" unit that caused some headaches.

Yes, exactly. In TURN mode, ASIN(1) results in 0.25, just like it results in 90 in DEG mode, 100 in GRAD mode or 1.57... in RAD mode. The basic idea behind it is that if the source or target representation isn't in any of the three traditional units in some kind of technical solution, why not work with a "neutral" unit (full circle = 1 turn)? Saves a step in ad-hoc conversions. I had implemented this in a software calculator a long time ago and found it to be intuitive and quite useful in practise. See:

Interesting read. I tend to agree, but it's not common practice by any means. I'll have to think about it some more before adding it. I want to be very cautions about unnecessary "feature creep" at this early stage, because I might run out of ROM space before finishing the important stuff. If there's space in ROM when everything else is finished, then minor things like this are easy to add.
