Conversion Formula
The formula to convert bar to psi is: psi = bar × 14.5038. It works because the conversion factor 14.5038 is derived from the relationship that 1 bar equals 14.5038 pounds per square inch. For example, if you have 2 bar, multiply 2 by 14.5038 to get 29.0076 psi.
Step-by-step math for 2 bar: 2 × 14.5038 = 29.0076 psi. This straightforward multiplication ensures accurate translation between the pressure units, making it simple to switch from metric to imperial measurement.
Conversion Example
- Convert 1 bar to psi:
- Multiply 1 by 14.5038: 1 × 14.5038 = 14.5038 psi.
- Convert 5 bar to psi:
- Multiply 5 by 14.5038: 5 × 14.5038 = 72.519 psi.
- Convert 0.5 bar to psi:
- Multiply 0.5 by 14.5038: 0.5 × 14.5038 = 7.2519 psi.
- Convert 10 bar to psi:
- Multiply 10 by 14.5038: 10 × 14.5038 = 145.038 psi.
- Convert 7.5 bar to psi:
- Multiply 7.5 by 14.5038: 7.5 × 14.5038 = 108.7785 psi.

Conversion Definitions
Bar
The bar is a metric unit of pressure, where 1 bar equals 100,000 pascals or approximately 14.5038 pounds per square inch, used to measure pressure in various industrial and scientific contexts.
Psi
Pounds per square inch, abbreviated as psi, measures pressure as the force in pounds exerted over one square inch of area, widely used in tire pressures, hydraulics, and other engineering applications.
Conversion FAQs
How accurate is the conversion from bar to psi?
The conversion is precise because it relies on the established factor that 1 bar equals exactly 14.5038 psi. Minor variations might occur depending on measurement tools, but mathematically, the conversion is accurate to four decimal places.
Can I convert negative bar values to psi?
Yes, negative pressure values in bar can be converted to psi using the same formula. Negative pressure might indicate a vacuum or below atmospheric pressure, so the psi value will also be negative, reflecting that state.
What are typical applications for converting bar to psi?
This conversion applies in tire pressure checks, hydraulic system measurements, scuba diving tanks, and industrial pressure gauges, where understanding pressure in different units is necessary for safety and accuracy.
