+                               if (mv < 0 || ik_unit == IK_KELVIN)
                                        printf("%jd", mv);
+                               else if (ik_unit == IK_FAHRENHEIT)
+                                       printf("%.1fF",
+                                           (mv - 2732.0) * 9 / 50 + 32.0);
                                else
                                        printf("%.1fC", (mv - 2732.0) / 10);

Ah, so then units are in tenths of a degree Kelvin?  Any special reason 
to prefer not showing it with printf("%.1fK", mv / 10); like the others?

cheers, Ian  (possibly jumping in out of my depth :)
