What is the average sea level pressure in the United States?
1013.25 mbar
Average sea-level pressure is 1013.25 mbar (101.325 kPa; 29.921 inHg; 760.00 mmHg).
What is standard sea level pressure?
about 14.7 pounds per square inch
atmosphere (atm) (atm) unit of measurement equal to air pressure at sea level, about 14.7 pounds per square inch. Also called standard atmospheric pressure.
What is standard sea level pressure in inches of mercury?
At sea level, standard air pressure in inches of mercury is 29.92.
What is a pound of pressure?
This is based on Imperial units such as the pound (lb) and inch (in) or foot (ft). The standard unit of pressure in this system is pound per square inch (PSI): the pressure resulting from a force of one pound applied to an area of one square inch. 1 PSI is approximately equal to 6895 Pa.
What is my sea level pressure?
Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.
What is the normal air pressure at sea level in MB?
1013.25 millibars
That means pressure applied by this air on the unit area would be 14.7 pounds per square inch. Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.
Is there a standard sea level?
How is sea level measured?
Sea level is primarily measured using tide stations and satellite laser altimeters. Tide stations around the globe tell us what is happening at a local level—the height of the water as measured along the coast relative to a specific point on land.
What is the average standard sea level pressure?
Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.
What is the normal air pressure at sea level?
The normal air pressure at sea level is 14.7 pounds per square inch.
How many pounds per square inch is 1 psi?
In SI units, 1 psi is approximately equal to 6895 N/m2. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure.
How are PSIA and psig related at sea level?
(Unless you live at high altitude or in a deep valley, the sea level value will work.) In other words, since atmospheric pressure at sea level is 14.7 PSIA, you subtract the PSIA of 14.7 from an atm pressure of 14.7 to equal zero PSIG (14.7 (PSIA) – 14.7 (atm) = 0).
What is the barometric pressure of one standard atmosphere?
The barometric pressure associated with one standard atmosphere at mean sea level is [you may round to nearest whole number]: (5 pts – 1 each) 1 atmosphere of pressure is equivalent to: 29.92 (or 30) inches of mercury 76.0 centimeters of mercury 14.7 (or 15) pounds per square inch (psi) 1013.25 (1000) millibar (mb) 34 feet of water
