Common Use Pressure Units

There are several units used to measure pressure. Here are some common pressure units and their conversions:

1. Pascal (Pa): 1 Pa = 1 N/m^2
2. Atmosphere (atm): 1 atm = 101,325 Pa
3. Bar (bar): 1 bar = 100,000 Pa
4. Pound per square inch (psi): 1 psi = 6,894.76 Pa
5. Millimeter of mercury (mmHg): 1 mmHg = 133.322 Pa
6. Torr: 1 Torr = 133.322 Pa

Common Use Conversion Factors

To convert between these units, you can use the following conversion factors:

1. To convert from Pa to atm: divide by 101,325
2. To convert from Pa to bar: divide by 100,000
3. To convert from Pa to psi: divide by 6,894.76
4. To convert from Pa to mmHg: divide by 133.322
5. To convert from Pa to Torr: divide by 133.322
