barometric pressure

[bar·ə′met·rik ′presh·ər]

atmospheric pressure, barometric pressure

The pressure exerted by the earth’s atmosphere; under standard conditions equal to 14.7 lb per sq in. (1.01 × 106 pascals) equivalent to the pressure exerted by a column of mercury 29.9 in. (76.0 cm) high.

barometric pressure

The local atmospheric pressure. It is normally measured by a barometer.
