Conversion Formula
The formula to convert bar to psi is: psi = bar * 14.5038. This works because 1 bar equals exactly 14.5038 psi, based on the international standard. By multiplying the number of bar by this factor, you get the pressure in psi. For example, for 0.3 bar: 0.3 * 14.5038 = 4.350 psi, which rounds to 4.355 psi.
Conversion Example
- Convert 1 bar to psi:
- Multiply 1 by 14.5038
- 1 * 14.5038 = 14.5038 psi
- Result: 14.5038 psi
- Convert 2.5 bar to psi:
- 2.5 * 14.5038 = 36.2595 psi
- Result: 36.2595 psi
- Convert 0.75 bar to psi:
- 0.75 * 14.5038 = 10.8779 psi
- Result: 10.8779 psi
- Convert 5 bar to psi:
- 5 * 14.5038 = 72.519 psi
- Result: 72.519 psi
- Convert 0.1 bar to psi:
- 0.1 * 14.5038 = 1.4504 psi
- Result: 1.4504 psi

Conversion Definitions
Bar
A bar is a metric unit measuring pressure, equal to 100,000 pascals, or roughly the atmospheric pressure at sea level. It is used in various fields to quantify pressure levels, especially in meteorology and engineering.
Psi
Pounds per square inch (psi) is an imperial pressure unit representing the force in pounds applied over one square inch area. It is common in the United States for measuring tire pressure, hydraulic systems, and other pressure-related applications.
Conversion FAQs
Why is the conversion factor 14.5038 used for bar to psi?
This factor is based on the precise relationship between the two units, where 1 bar equals exactly 14.5038 psi. This standard ensures consistency and accuracy in pressure calculations across scientific and industrial contexts.
Can I convert any pressure from bar to psi manually?
Yes, multiplying the bar value by 14.5038 will give the equivalent psi. For quick estimates, some use 14.5 as a rough factor, but for precise work, use the full 14.5038 multiplier.
Is 0.3 bar a safe pressure for car tires?
Typically, car tires are inflated between 2.0 and 3.0 bar, so 0.3 bar is too low for safe driving conditions and could cause tire damage or unsafe driving. Always check your vehicle’s recommended pressure.
What other units can I convert from bar?
Pressure units such as pascals, atmospheres, psi, and kilopascals can be converted from bar using their respective conversion factors, facilitating measurements across different systems and standards.
