What is Bar?

Bar is a metric unit of pressure that is equal to 100,000 Pascals, and is just a little less than the average atmospheric pressure on Earth at sea level. It is not a part of the International System of Units (SI), but is widely used around the world, and is legally recognized in countries of the European Union.

1 bar is therefore equal to:

• 100 kPa (in SI units)
• 1 × 105 N/m2 (alternative representation in SI units)
• 1,000,000 Ba (barye) (in cgs units)

and approximately equal to:

• 0.987 atm
• 14.5038 psi absolute
• 29.53 inHg
• 750.06 mmHg
• 750.06 Torr
• 1,019.72 cmH2O

Bar can be used as an absolute pressure value that includes atmospheric pressure - bar absolute denoted as Bar(a), or as pressure relative to atmospheric pressure - bar gauge denoted as Bar(g). Atmospheric pressure at sea level equals to 1.01325 bar. So for example, a tire pumped to 3 bar above local atmospheric pressure will have a pressure of 3 bar(g) or 3 + 0.01325 = 3.01325 bar(a).

Bar units can be used as:

• megabar (Mbar) = 1,000,000 bar
• kilobar (kbar) = 1,000 bar
• hectobar (hbar) = 100 bar
• decabar (dabar) = 10 bar
• decibar (dbar) = 0.1 bar
• centibar (cbar) = 0.01 bar
• millibar (mbar) = 0.001 bar
• microbar (µbar) = 0.000001 bar

Bar to Psi Converion

There are 14.50377 psi in bar. So it is easy to convert bar to psi using a simple formula: psi unit = bar unit multiplied by 14.50377. You can use our bar to psi converter, or bar to psi conversion chart.

What is Psi?

Psi, also known as pound per square inch or pound-force per square inch, is a unit of pressure or of stress based on avoirdupois units. It is the pressure result when a force of one pound-force is applied to an area of one square inch.

1 psi is therefore equal to:

• 6894.757 Pa

and approximately equal to:

• 0.068046 atm
• 0.0689476 bar absolute
• 51.71493 Torr

Psi can be used as an absolute pressure value that includes atmospheric pressure - psi absolute denoted as Psi(a), or as pressure relative to atmospheric pressure - psi gauge denoted as Psi(g). Atmospheric pressure at sea level equals to 14.7 psi. So for example, a tire pumped to 35 psi above local atmospheric pressure will have a pressure of 35 psi(g) or 35 + 14.7 = 49.7 psi(a).

Psi units can be used as:

• Megapound per square inch (msi) = 1,000,000 psi
• Kilopound per square inch (ksi) = 1,000 psi

Psi to Bar Converion

There are 0.0689476 bar in psi. So it is easy to convert psi to bar using a simple formula: bar unit = psi unit multiplied by 0.0689476. You can use our psi to bar converter, or psi to bar conversion chart.
