How much is a standard atmospheric pressure/( Mpa） ？

Standard atmospheric pressure is in the standard atmospheric conditions of sea level pressure, its value is 101. Is 325 kpa pressure unit, as an ATM. Once the standard temperature and pressure in the chemical, STP) Definition of 0 & deg; C ( 273. 15 k) And 101. 325 kpa ( 1 atm) , but in 1982 the IUPAC will & other; The standard pressure & throughout; Redefined as 100 kPa. 1 standard atmosphere = 760 mm hg = 76 cm hg = 1. 01325× 10 ^ 5 pa = 10。 339 m water column. 1 standard atmosphere = 101325 N / ㎡. （ In the calculation is usually 1 standard atmosphere = 1. 01× 10^5 N/㎡) 。 100 kpa = 0。 1 mpa






a standard atmospheric pressure is 1. 5 013 square 1 PASCAL. 01× 10 ^ 5 PASCAL


standard atmospheric pressure conversion formula:



( 1) 1 kg is equal to 0. 1 mpa is a standard atmospheric pressure, a kilo is short for one kilogram of force per square centimeter, one kilogram of force equal to 9. 8 Newton.



so: one kilogram of force per square centimetre = ( 9. 8/0. 0001). Pa = 0。 098 mpa is approximately equal to 0. 1 mpa, while a standard atmospheric pressure = 1. 01325 x100000pa is approximately equal to 0. 1MPa. = 105 pa



so: 1 = 10 mpa = 10 kilograms force ㎏ / c ㎡ 1 mpa = 10 standard atmospheric pressure 0. 1 mpa = 1 standard atmosphere



( 2) Or according to the engineering conversion is one of the most commonly used in the atmospheric pressure = 10 m water column = = 0 1 kg force. 1 mpa
