Pa is the metric unit for pressure, Pascal. It is one Newton per square meter. Atmospheric pressure is approximately 101 kPa (101 000 Pa), which is 14.7 psi (pounds per square inch) in Imperial units. The air pressure in car tires is usually about twice that (32 psi, 220 kPa).
One formula used to convert psi to bar is: 1 psi = (32.174 lbm /1 lbf s2)x(0.45359237 kg /1 lbm)x(144 in2/1 ft2)x(1 ft /0.3048 m) x(1 m s2 /105 kg) = 0.06894747 bar So 1 bar = 14.503795 psi The Math behind it. As psi is an imperial unit and bar is metric unit, we some constants 1 lb = 0.45359237 kg 1 ft = 0.3048 m 1 ft2 = 12 in x 12 in = 144 in2 And we have to rearrange some units 1 bar = 105 Pa = 105 Nm-2 And N = kg ms-2 so 105 Pa = 105 kgm-1s-2 Also note when applying newton's second law using imperial units we need to use a gravity constant 32.174 lbm /1 lbf s2 Metric m x a = F 1 kg x 9.81 ms-2 = 9.81 N Imperial units m x a = F 1 lbm x 32.174 fts-2 ≠ 32.174 lbf need to use gravity constant gc m x (a/gc) = F 1 lbm x (32.174 fts-2 / (32.174 lbm /1 lbf s2) = 1 lbf

MPa is a metric (SI) unit for pressure, or force per unit area. Pa is the Pascal, which is one Newton of force applied to one square meter of area (1 N/m2). MPa is a mega-Pascal, or one million Pascals. Since atmospheric pressure is 101 000 pA, or 101 kPa(approximately 14.7 psi), this is approximately 9 atmospheres (around 150 psi).
swap (int *pa, int *pb) { *pa ^= *pb; *pa ^= *pa; *pa ^= *pb; }
100,000 (just type "1 bar in pascals" into google)
101.3 kPa=100 Pascals 101.3 kPa=1.00atm=760 mmHg=25.4 in Hg=14.7psi=100 Pa
Multiply psi by 0.006894759086775369 to convert from psi to MPa. ex: 1000 psi = 1000 x 0.006894759086775369 = 6.89 MPa http://www.chapelsteel.com/psi-mpai.html
There are several units for used to indicate pressure. The SI unit is the Pascal (Pa). The English unit is psi which equals 6,891 Pa. A Bar is equal to 100 kPa. A Tor is equal to 1 kPa. An atmosphere (atm) is equal to 101.3 kPa.
1 bar is equal to 100000 Pa. If you're interested, 10000 Pa is equal to 100 kPa which is the same as 0.1 MPa.

The SI unit is pascals (Pa), but it can also be measured in psi, torr, bar, atm, and mmHg. There are also many others as can be seen in this online converter: http://www.coleparmer.com/Techinfo/converters/commpressure.asp
pascal (Pa) bar (bar) technical atmosphere (at) atmosphere (atm) torr (Torr) pound-force per square inch (psi) - still in widespread use in the US and Canada, notably for cars.
The SI unit for pressure is the pascal (Pa), equal to one newton per square metre. other units: pound per square inch (psi) = 0.0339 Pa pound per square foot (psf) = 4.882 Pa bar = 100 kPa mbar (millibar) = 0.001 ba = 100 Pa standard atmosphere = 101325 Pa
Psi (pounds per square inch) is a unit of pressure commonly used in the United States, while pascals (Pa) are the SI unit of pressure. 1 psi is approximately equal to 6895 Pa.
1000 psi is 6.895 MPa (mega pascals) where a Pa is 1 Newton/m2; thos 30 psi = 30/1000 x 6895000 = 206,850 N/m2
