Issues with pressure unit conversions
Thread Content
Yesterday, when trying to convert between bars and pascals, I looked it up online, but ended up confused; I’m not clear about how to perform this conversion. I’ve seen on the internet that 1 bar is equal to 105 Pa. However, it’s also stated that 1 physical atmosphere equals 101.325 kPa, 14.696 psi, and 1.0333 bar. So what exactly is the conversion rate between bars and Pascals?
It depends on how you use it; in engineering, 1 bar is generally used, which equals 100 Pa – a less precise value. Of course, for theoretical research, greater precision is required, but this is rarely applied in practice.
Is this doubtful? 1 bar ≈ 1 atmosphere = 101325 Pa. I’ve never seen 1 bar = 105 Pa.
The second floor is correct. In engineering, pressures are generally rounded off, as there is a significant difference between operating conditions and design conditions, so such high precision is not necessary.
The original poster must have made a mistake; 1 bar = 100,000 Pa, and the 5 in that number should be a superscript, meaning 10 to the power of 5
Is 1 bar equal to 105 KPa? In engineering, 1 bar is defined as 0.1 MPa = 100,000 Pa = 1.0197 kg/cm2.
It seems the unit wasn’t specified; isn’t 1 bar equal to 100 Pa?
1 MPa = 10 kg = 10 bar = 100 m of water column = 7600 mmHg column. 1000 psi = 7 MPa. This is the way calculations are generally done in engineering
1 bar is approximately equal to 100,000 Pa
Pressure: 1 bar = 105 Pa. 1 kPa = 0.145 psi = 0.0102 kgf/cm2 = 0.0098 atm. 1 psi = 6.895 kPa = 0.0703 kgf/cm2 = 0.0689 bar = 0.068 atm. 1 physical atmosphere = 101.325 kPa = 14.696 psi = 1.0333 bar. 1 engineering atmosphere = 98.0665 kPa. 1 mmH2O = 9.80665 Pa. 1 mmHg = 133.322 Pa. 1 Torr = 133.322 Pa. 1 dyn/cm2 = 0.1 Pa
Did the OP read what’s above? That’s probably the case.
It also depends on what you use it for; the precision varies
