The Ohio Department of Job and Family Services used wage updating factors from March 2015 to further update the data to a more current time period. The updated data contained in this report are not official Bureau of Statistics data series, nor have they been validated by BLS.
Barometric pressure (also known as atmospheric pressure) is the force exerted by the atmosphere at a given point. It is known as the weight of the air. A barometer measures barometric pressure. Measurement of barometric pressure can be expressed in millibars(mb) or in inches or millimeters of mercury (Hg). Normal pressure at sea level is 1013.3 millibars or 29.92 inches of mercury. Fluctuations in barometric pressure are usually a sign of weather conditions.
Atmospheric and Gauge Pressure. 1  Absolute pressure: The total pressure exerted on a system referenced to zero Pascals, and equal to the gauge pressure plus atmospheric pressure. 2  Gauge Pressure: Pressure referenced to one atmosphere, and is the pressure actually shown on the dial of a gauge that registers pressure relative to atmospheric pressure. For example, an ordinary pressure gauge reading of zero does not mean there is no pressure, it means there is no pressure in excess of atmospheric pressure.
