About bars and pounds-force per square inch

Bar (bar)

A bar is exactly 100,000 pascals, close to atmospheric pressure. It is used for tire pressure, scuba diving and industrial gauges.

Pound-force per square inch (psi)

Pound-force per square inch is about 6,894.757 pascals. It is used for tire pressure and hydraulic and pneumatic systems in the US.

Both are units of pressure; the base unit used internally is Pa.

Notes

bar to psi FAQs

How do I convert bars to pounds-force per square inch?

Multiply the number of bars by 14.50377377 to get pounds-force per square inch. For example, 25 bar × 14.50377377 = 362.594 psi.

How many pounds-force per square inch are in one bar?

1 bar = 14.50377377 psi and 1 psi = 0.06894757293 bar. To go the other way, use the pounds-force per square inch to bars converter.

How many pounds-force per square inch are in 2 bars?

2 bar = 29.0075 psi, rounded to 6 significant digits. Change the value in the converter above for any other amount.

How many pounds-force per square inch are in 10 bars?

10 bar = 145.038 psi, rounded to 6 significant digits.

Is the bar to psi conversion exact?

The ratio is exact by definition, but its decimal form does not end (14.503773773… to 12 significant digits). The converter keeps full precision internally and rounds only the displayed answer, which you can set from 4 to 12 significant digits.

What is the difference between bars and pounds-force per square inch?

A bar is exactly 100,000 pascals, close to atmospheric pressure. It is used for tire pressure, scuba diving and industrial gauges. Pound-force per square inch is about 6,894.757 pascals. It is used for tire pressure and hydraulic and pneumatic systems in the US.

Does this handle gauge pressure (psig) or absolute pressure (psia)?

The converter changes units only and does not add or remove atmospheric pressure. A reading of 30 bar is 435.113 psi in whichever reference (gauge or absolute) it was measured; to move between gauge and absolute, add or subtract about 14.6959 psi (one standard atmosphere) yourself.
