One is the “temperature and pressure system” represented by the United States and represented by the allowable working pressure at a certain temperature There are two types of valve systems: one is the “nominal pressure” system represented by Germany (including my country) based on the allowable working pressure at room temperature (100 degrees in my country and 120 degrees in Germany). Pressure 1 bar (bar) = 10^5 Pa (Pa) 1 dyne/cm2 (dyn/cm2) = 0.1 Pa (Pa)ġ Torr (Torr) = 133.322 Pa (Pa) 1 millimeter of mercury (mmHg) = 133.322 Pa (Pa)ġ mm water column (mmH2O) = 9.80665 Pa (Pa)ġ engineering atmospheric pressure = 98.0665 kilopascals (kPa)ġ kilopascal (kPa) = 0.145 lbf/in2 (psi) = 0.0102 kgf/cm2 (kgf/cm2) = 0.0098 atmospheric pressure (atm)ġ pound force/inch 2 (psi) = 6.895 kilopascal (kPa) = 0.0703 kilogram force / centimeter 2 (kg/cm2) = 0.0689 bar (bar) = 0.068 atmospheric pressure (atm)ġ physical atmospheric pressure (atm) = 101.325 kilopascals (kPa) = 14.696 pounds per inch 2 (psi) = 1.0333 bar (bar) In addition, there are Pa (Pascal, one Newton acts on one square meter), KPa, Mpa, Bar, millimeter water column, millimeter mercury column and other pressure units.ġ bar (bar) = 0.1 MPa (MPa) = 100 kilopascal (KPa) = 1.0197 kg/cm²ġ standard atmospheric pressure (ATM) = 0.101325 MPa (MPa) = 1.0333 bar (bar)īecause the difference in units is very small, you can write it like this:ġ bar (bar) = 1 standard atmospheric pressure (ATM) = 1 kg/cm2 = 100 kilopascals (KPa) = 0.1 megapascals (MPa)ġ standard atmospheric pressure (atm) = 14.696 pounds per inch 2 (psi) This unit is like the Fahrenheit temperature scale (F). The commonly used unit abroad is “Psi”, and the specific unit is “lb/in2″, which is “pound per square inch”. One kilogram of pressure means that one kilogram of force acts on one square centimeter. In China, we generally describe the pressure of gas in “kg” (rather than “jin”), and the body unit is “kg/cm^2″. Converting all the units to metric units yields:Ĭountries such as Europe and the United States are accustomed to using psi as a unit Psi to MPa conversion, psi is a pressure unit, defined as pounds per square inch, 145psi=1MPa, PSI is called Pound sper square inch in English.
