# What Is A Standard Atmospheric Pressure (Mpa)?

- Oct 26, 2018-

The standard atmospheric pressure is the sea level pressure under the standard large = condition, and its value is 101.325 kPa, which is the unit of pressure, which is recorded as atm. In the chemical, the standard temperature and pressure (STP) were defined as 0 ° C ( 273.15 K) and 101.325 kPa ( 1 atm), but in 1982 IUPAC redefines the standard pressure to 100 kPa. 1 standard atmospheric pressure = 760 mm Hg = 76 cm Hg = 1.01325 x 10^5Pa = 10.339 m water column. 1 standard atmospheric pressure = 101325 Nm. (In the calculation, it is usually 1 standard large pressure = 1.01x 10^5 Nm7). 100kPa=0.1MPa

A standard atmospheric pressure is 1.013X10 5th square pascal 1.01x10^5 Pascal

Standard atmospheric pressure conversion formula:

(1) 1 kg equals 0.1 Mpa equals one standard atmospheric pressure, - kg is the abbreviation of one kilogram force per square centimeter, and - kilogram force equals 9.8 Newtons.

Therefore: one kilogram force per square centimeter = (98/0 0001) Pa = 0.098 MPa is approximately equal to 0.1 MPa, and a standard atmospheric pressure = 1.01325100000 Pa is also approximately equal to 0.1 MPa. = 105 Pa

Therefore: 1MPa = 10 kg force = 10kg / cm?

1MPa=10 standard atmospheric pressure 0.1MPa=1 standard atmospheric pressure

(2) or according to the most commonly used conversion in the project is 1 atmosphere = 10m water column = 1 kg force = 0.1MPa
