# Bar to Psi, Psi to Bar

## Convert bar to psi, convert psi to bar. Bar to psi conversion, psi to bar conversion.

#### 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.
