Mega Pascal - measurement of pressure
The atmospheric pressure at sea level is typically around 101.3 kilopascals (kPa).
The atmospheric pressure at sea level is typically around 1013.25 hPa, which is equivalent to 101.325 kPa.
Atmospheric pressure is the force exerted by the weight of the air in the atmosphere, while water pressure is the force exerted by the weight of water in a body of water. Atmospheric pressure decreases with altitude, while water pressure increases with depth. Atmospheric pressure is measured in units like atm or pascals, while water pressure is typically measured in units like pounds per square inch (psi) or pascals.
It refers to the atmospheric pressure which, in this case, is measured in inches of Mercury on a mercury barometer
Vacuum is measured using a unit called Torr, which is commonly used in scientific and industrial settings. Another unit used for vacuum measurement is Pascal (Pa), which is the SI unit of pressure. Vacuum levels are typically expressed in Torr or Pa to indicate the degree of pressure below atmospheric pressure.

Atmospheric pressure is typically measured in units of millibars (mb) or kilopascals (kPa). The standard unit for atmospheric pressure is the pascal (Pa), with 1 atmosphere being approximately 1013.25 hPa or 101.3 kPa.
American units of air pressure include pounds per square inch (psi) and inches of mercury (inHg). These units are commonly used in weather reports and aviation to measure atmospheric pressure.
The unit of measurement for pressure is the pascal (Pa) in the International System of Units (SI). Other common units for pressure include atmospheres (atm), pounds per square inch (psi), and millimeters of mercury (mmHg).
