If you review the NASA Inspector General's report on NASA's request for a Customary exception on the Constellation program, he cites the USAF's reluctance to metricate as why NASA has trouble getting the aerospace industry to go along with metric. The USAF is specifically cited as the least metric of US military services. The Army has been metric for sometime, the Navy is coming around and has recently built some all metric ships, the Air Force, not so much.

The A330 is of course an all metric plane. The US military I understand works in metric. The rival Boeing 767 tanker is of course a non-metric plane. I wonder if anyone knows (a) what units are used (or primarily used) in the bidding documents; and (b) following on from this, what units will be used in the aircraft's operation and maintenance?
