In a previous article, Frank Foss said:
The controller (tower?) says: "QNH one-zero-zero-eight"
This is the local altimeter setting in hPa (hecto Pascal)

Lindbergh replies: "three-zero-zero-eight"
Which would be the "normal" / US setting, in inches of mercury.

My favourite hPa/inch thing is in my sig.
