Technically, millimeters of Mercury. These days, though, inches of Mercury is much more common. When the weatherman says that the barometer is 29.7, they are referring to the number of inches that the air pressure will force mercury to go up inside a glass tube. These days, they don't use the actual mercury column so much, but rather mechanical barometers.

Because it has a high density... meaning that the volume increase or decrease due to altitude change is can be viewed in a practical sized barometer. If water, which had a much lower density, was used instead of Mercury, the barometer must be at least 15m high.
