Everybody in the USA uses metric. Also we use English customary. Also secretly Canadian (Robertson) whenever the SAE isn’t looking.
But we don’t use those silly English pipe threads like metric countries do (except on NATO ships, whoops!)
EDIT: I apologize for derailing the thread and will post no more on America’s greatness in measuring system technologies today. Please resume commenting on Mr. Zuckerberg’s congressional testimony, if you would!
