Who is god's name works in 16th of an inch!? This just has to be the world famous American accuracy system in operation, same system that put the men on the moon to one 32th of an inch accuracy, ho, ho, ho. In these days of digitalisation and hi-tech how come Americans are still using systems of measurement from the 19th century, and can't let go of it! Is this not slightly embarrassing to be American when you are confronted with ANY other country in the world which has been using decimal since last CENTURY! And they are pretending to be serious. 2018 06 10 17:59:53 MET
