How to convert bars to pounds per square inch?

To convert bar to psi (pounds per square inch), multiply the pressure in bar by 14.5038.

Formula:

psi = bar × 14.5038

Example:

2 bar × 14.5038 = 29.0076 psi

For a quick reverse check, you can convert psi to bar by dividing by 14.5038:

bar = psi ÷ 14.5038

Use this conversion when you need to match pressure readings across tools, gauges, and specs that list bar or psi.

Frequently asked questions

How many PSI are in 1 bar?

1 bar equals 14.5038 PSI (pounds per square inch). This value comes from the standard definitions of bar and PSI.

How do you convert bar to PSI?

Multiply the pressure in bar by 14.5038 to get PSI.
Formula: PSI = bar × 14.5038

What is the fastest way to estimate bar to PSI?

Use 15 PSI per bar for a quick estimate. It’s close enough for rough checks, but it won’t match exact results.

What is 2 bar in PSI?

2 bar = 2 × 14.5038 = 29.0076 PSI.
Rounded: 29.01 PSI

What is 3 bar in PSI?

3 bar = 3 × 14.5038 = 43.5114 PSI.
Rounded: 43.51 PSI

What is 5 bar in PSI?

5 bar = 5 × 14.5038 = 72.519 PSI.
Rounded: 72.52 PSI

What is 10 bar in PSI?

10 bar = 10 × 14.5038 = 145.038 PSI.
Rounded: 145.04 PSI

What is 0.5 bar in PSI?

0.5 bar = 0.5 × 14.5038 = 7.2519 PSI.
Rounded: 7.25 PSI

Can you convert PSI to bar too?

Yes. Divide PSI by 14.5038 to get bar.
Formula: bar = PSI ÷ 14.5038

Why do bar and PSI give different numbers for the same pressure?

They use different unit sizes. Bar is a metric pressure unit, while PSI is based on force over one square inch. They measure the same thing, just in different units.

Is bar the same as atmospheric pressure?

Not exactly. Standard sea-level pressure is about 1.01325 bar, which is about 14.6959 PSI. So 1 bar is slightly lower than standard atmosphere.

Does temperature affect bar-to-PSI conversion?

No. The conversion is a fixed math relationship between units. Temperature can change the pressure in a system, but it doesn’t change how bar converts to PSI.

Are “bar” and “barg” the same when converting to PSI?

No. bar often means absolute pressure, while barg means gauge pressure (relative to air pressure). Convert the number the same way, but make sure you know if it’s absolute or gauge, since the starting value may differ.

Is the conversion the same for air, water, and oil pressure?

Yes. Pressure units convert the same no matter the fluid. The fluid changes how pressure behaves in a system, but not the unit conversion.

How many decimal places should you use for bar to PSI?

For most day-to-day uses, 2 decimal places is enough. For lab work or calibration, use more digits, like 14.5038.
