I am exactly 1 unit in length of myself, the preferred measurement of my kingdom and its three subjects (the dog uses metric, she's an Australian Shepherd).
This loosely translates to 1/1000th of a frequent flier mile, 0.00111 FFmi, or one millifrequentfliermile after fees and taxes. Thus, I am 1 mffim, or "miffim", because...palindrome.
This is why I frequently get lost: incompatible units.
