2.5 psi equals approximately 0.1724 bar.
This conversion shows that pressure measured in pounds per square inch (psi) can be translated into bar, a metric unit. Using the conversion factor, 1 psi is equal to about 0.0689476 bar. Multiplying 2.5 by this factor gives the result in bar.
Pressure Conversion from psi to bar
To convert psi to bar, multiply the psi value by 0.0689476. This factor is derived from the exact definition where 1 psi equals 6894.76 pascals, and since 1 bar equals 100,000 pascals, dividing 6894.76 by 100,000 gives the conversion factor. For example, for 2.5 psi: 2.5 × 0.0689476 = 0.1724 bar.

Conversion Formula
The formula to convert psi to bar is straightforward: bar = psi × 0.0689476. This works because each psi equals approximately 0.0689476 bar. So, if you have a pressure of 2.5 psi, multiplying it by this number gives the equivalent in bar. Example: 2.5 × 0.0689476 = 0.1724 bar.
Conversion Example
- Convert 5 psi to bar:
- Multiply 5 by 0.0689476.
- 5 × 0.0689476 = 0.3447 bar.
- Convert 10 psi to bar:
- Multiply 10 by 0.0689476.
- 10 × 0.0689476 = 0.6895 bar.
- Convert 1 psi to bar:
- Multiply 1 by 0.0689476.
- 1 × 0.0689476 = 0.0689 bar.
- Convert 7.5 psi to bar:
- Multiply 7.5 by 0.0689476.
- 7.5 × 0.0689476 = 0.5171 bar.

Conversion Definitions
psi
Psi, pounds per square inch, measures pressure by indicating how many pounds of force are applied over one square inch of area. It’s commonly used in the US for tire pressures, plumbing, and other pressure measurements, representing force per unit area.
bar
Bar is a metric pressure unit equal to 100,000 pascals. It measures pressure based on the force exerted over an area, often used in meteorology, engineering, and industrial applications to quantify pressure levels in liquids and gases.
Conversion FAQs
What does 2.5 psi mean in terms of bar?
It means that pressure of 2.5 pounds per square inch is roughly equivalent to 0.1724 bar, indicating a low to moderate pressure level depending on the context, such as tire inflation or industrial systems.
Can I use the same conversion factor for all psi values?
No, the conversion factor stays the same, but calculations vary with the psi value. For larger or smaller psi readings, multiply by 0.0689476 to find the corresponding pressure in bar, regardless of the magnitude.
How accurate is this conversion?
The conversion uses a precise factor based on the exact definitions of psi and bar, so it provides high accuracy for most practical purposes, including scientific and engineering calculations, within a negligible margin of error.
