While I do understand your frustration because I have felt the pinch myself, the metric system has been actively and voluntarily used in the scientific community for decades, by the American military since before WWII and in some American sporting events since the 1960s.
I understand all that, but using metric as a numeric language when communicating to the broad American public is guaranteed to inflict blanks of non-comprehension on most recipients.
I honestly appreciate it when I'm watching a science program and a scientist takes the care to speak to his American audience in units of measure they instantly recognize. Being somewhat of a junkie for that sort of programming, I know that he's consciously going the distance to achieve simple understanding on the part of his viewers.
The ubiquitous usage of metric units of measure in the common dialog is a pet peeve of mine. For me, it's just another invalidation and rejection of my American culture by the same forces that don't like my language or my heritage on this continent.
They're forcing me to be illiterate and innumerate in my own country.
