feet and inches input request

 From:  Lemo (LEMONNADO)
I recently received a machine part.... a drive shaft.. 1/2 inch diameter, with M5 metric threaded holes on each end.
Each hole is 1 inch deep. Ahhhahahahaha (hysterical laughter). Made in China....

We are going to heck in a handbasket! Let's mix and match....

Or as it stands on a sign at the Long Island Express way: Islip Airport -> 1 Mile/1 Km
