My Vacuum gauge calibrated in "Oodles Of Suck".
My cylinder head temperature calibrated in "Amount of Cosiness"
My air speed gauge calibrated in "Getting there: Fast/Slow".
My fuel gauge calibrated in percentage of "Beer In Glass".
...and the cost of my AVGAS paid in "Cow Turds".
Now wouldn't that make a nice change from "Metric" measurement...
