About Bar to PSI & Conversion Table

Bar

Definition: A bar is a unit of pressure defined as 100,000 pascals. It is slightly less than the average atmospheric pressure on Earth at sea level, which is 1.01325 bar.

History/Origin: The term “bar” comes from the Greek word “baros,” meaning weight. It was introduced by the Norwegian meteorologist Vilhelm Bjerknes in the early 20th century.

PSI

Definition: PSI (pound per square inch) is a unit of pressure or stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

History/Origin: The PSI unit is derived from the imperial system, which is widely used in the United States. It is commonly used to measure pressure in various applications, including tire pressure, gas storage, and industrial processes.

Current Use: PSI is widely used in various industries, including automotive, aerospace, and manufacturing, to measure pressure levels in different systems.

Conversion Formula:
To convert bar to PSI, use the following formula:
PSI = Bar * 14.5038
This means one bar is approximately equal to 14.5038 PSI.

Bar to PSI (bar to psi) Converter FAQs

How do I convert 1 bar to psi?

To convert 1 bar to psi:

1. Know that 1 bar is approximately 14.5038 psi.

2. Use the conversion formula: amount in psi = amount in bar × 14.5038.

3. Apply the formula: 1 bar × 14.5038 ≈ 14.5 psi.

Thus, 1 bar is approximately 14.5 psi.

How do I convert 50 psi to bar?

To convert 50 psi to bar:

1. Remember that 1 psi is approximately 0.0689476 bar.

2. Use the formula: amount in bar = amount in psi × 0.0689476.

3. Apply the formula: 50 psi × 0.0689476 ≈ 3.45 bar.

So, 50 psi is approximately 3.45 bar.

How can I measure psi without a gauge?

If you need to measure psi without a gauge, try these methods:

1. Use a known weight and area. Pressure is force per unit area, so you can calculate psi if you know the force in pounds and the area in square inches.

2. Use a simple manometer. A U-tube manometer can measure pressure differences, which you can convert to psi.

3. Use a Bourdon tube pressure gauge. These are mechanical devices that can measure pressure and are often found in older or industrial equipment.

How do bar compare to psi?

One bar is approximately 14.5038 psi. Conversely, one psi is about 0.0689476 bar.

For reference, 2 bar is about 29.01 psi, and 5 bar is about 72.52 psi.

Can I use your tool to convert between bar and psi?
