I'd like more options, if that's possible. :-) We could use "inches" for Hero System (which uses hexes as 2m, but all game terminology is really in inches). The straight line in the hexes also seems to measure some strange units when you go further out (it assumes any angular movement gets the increase like squares do, I think, and moving off a side of a hex at 60 degrees in a straight line across hexes gets weird numbers, even when hexes are in a straight line).
