145 psi equals approximately 10.0 bar.
The conversion from psi (pounds per square inch) to bar involves multiplying the psi value by 0.0689476. For 145 psi, multiplying gives 145 × 0.0689476 ≈ 10.0 bar. This conversion helps in understanding pressure measurements across different unit systems, especially in engineering contexts.
What is the Conversion from psi to bar?
The process of converting psi to bar involves the use of a multiplication factor, which is approximately 0.0689476. Since psi measures pressure in pounds-force per square inch, and bar measures pressure in metric units, multiplying the psi value by this factor converts it to bar. For example, to convert 145 psi, you multiply 145 by 0.0689476, resulting in about 10.0 bar. This formula works because 1 psi equals 0.0689476 bar, based on the conversion between imperial and metric pressure units.

Conversion Formula
The formula to convert psi to bar is based on the conversion factor 0.0689476. Each psi is equivalent to 0.0689476 bar, so multiplying the psi value by this number gives the pressure in bar. For example, if you have 200 psi, multiplying 200 by 0.0689476 results in 13.78952 bar. This works because the units are scaled according to their definitions: 1 psi equals 6894.76 Pascals, and 1 bar equals 100,000 Pascals, leading to the conversion factor.
Conversion Example
- Convert 100 psi to bar:
- Multiply 100 by 0.0689476
- 100 × 0.0689476 = 6.89476 bar
- Convert 200 psi to bar:
- Multiply 200 by 0.0689476
- 200 × 0.0689476 = 13.78952 bar
- Convert 50 psi to bar:
- Multiply 50 by 0.0689476
- 50 × 0.0689476 = 3.44738 bar
- Convert 175 psi to bar:
- Multiply 175 by 0.0689476
- 175 × 0.0689476 = 12.06653 bar
- Convert 300 psi to bar:
- Multiply 300 by 0.0689476
- 300 × 0.0689476 = 20.68428 bar

Conversion Definitions
Psi: Pounds per square inch, a measurement of pressure showing force exerted in pounds over an area of one square inch, used mainly in the imperial system for measuring pressures like tire inflation or hydraulic systems.
Bar: Metric unit of pressure, equal to 100,000 Pascals, used worldwide especially in Europe and for scientific, industrial, and engineering purposes to quantify pressure levels.
Conversion FAQs
How accurate is the conversion from psi to bar?
The conversion is accurate as long as the conversion factor 0.0689476 is used. Minor variations may happen due to rounding, but for most practical purposes, it provides a reliable estimate of pressure in bar from psi values.
Can I convert other pressure units to bar using the same formula?
No, different units have different conversion factors. For example, converting from atmospheres or Pascals requires different multipliers. Always ensure you use the correct factor for each specific unit before converting to bar.
Why do different countries prefer psi or bar for pressure measurements?
Preferences depend on regional standards, historical practices, and the types of applications. The imperial system, including psi, is common in the US, while the metric system, including bar, is preferred in Europe and scientific communities.
What safety pressure levels in bar should I consider for industrial equipment?
This varies based on the equipment and application. Always consult manufacturer guidelines or industry standards. Generally, pressures below 10 bar are common for many industrial systems, but higher pressures may be necessary for specialized machinery.
