Conversion Formula
The conversion from bar to psi uses the formula: psi = bar × 14.5038. This works because 1 bar is exactly equal to 14.5038 psi, which is a standardized conversion factor based on the definition of these pressure units. To convert, multiply the number of bars by 14.5038. For example, 3.7 bar equals 3.7 × 14.5038, which results in approximately 53.66 psi. This consistent ratio allows for quick conversions between these measurement systems.
Conversion Example
- Convert 2 bar to psi:
- Multiply 2 by 14.5038
- 2 × 14.5038 = 29.0076 psi
- Result: 2 bar equals approximately 29.01 psi
- Convert 5.5 bar to psi:
- Multiply 5.5 by 14.5038
- 5.5 × 14.5038 = 79.7709 psi
- Result: 5.5 bar equals approximately 79.77 psi
- Convert 0.5 bar to psi:
- Multiply 0.5 by 14.5038
- 0.5 × 14.5038 = 7.2519 psi
- Result: 0.5 bar equals approximately 7.25 psi
- Convert 10 bar to psi:
- Multiply 10 by 14.5038
- 10 × 14.5038 = 145.038 psi
- Result: 10 bar equals approximately 145.04 psi

Conversion Definitions
Bar
A bar is a metric unit of pressure, defined as 100,000 pascals, roughly equal to atmospheric pressure at sea level. It is used in various scientific and industrial contexts to measure force per unit area, especially in Europe and in technical applications.
Psi
Pounds per square inch (psi) is a pressure unit in the imperial system, measuring force in pounds applied over an area of one square inch. It is common in the United States for applications like tire pressures, hydraulics, and plumbing systems.
Conversion FAQs
How accurate is the conversion from 3.7 bar to psi?
The conversion uses a fixed factor of 14.5038, making it highly accurate. Minor variations might occur in practical measurements due to instrument calibration, but mathematically, 3.7 bar equals approximately 53.66 psi.
Can I convert other pressure units to psi using the same formula?
Yes, but you need the correct conversion factor for each unit. For example, kilopascals to psi requires multiplying by 0.145038. The formula varies depending on the original unit, so ensure to use the right factor.
Why do different pressure units require different conversion factors?
Because pressure units are based on different measurement systems—metric or imperial—they have unique definitions. Conversion factors align these units, allowing for accurate translation from one system to another.
What equipment can measure pressure in psi and bar?
Pressure gauges and transducers often display measurements in either psi or bar. Some digital devices allow switching between units, providing versatility for various industrial, automotive, or scientific applications.
