2.5 psi is approximately equal to 0.1724 bar.
Table of Contents
This conversion is done by multiplying the pressure in pounds per square inch (psi) by the conversion factor 0.0689476, which is the amount of bar in one psi. So, 2.5 psi x 0.0689476 = 0.1724 bar, showing how many bar the psi value corresponds to.
Conversion Result
The pressure of 2.5 psi converts to about 0.1724 bar, a unit used in metric systems for measuring pressure. This allows for easier comparison or use in countries or industries where bar is the standard measurement.

Conversion Formula
The formula for converting psi to bar is straightforward: bar = psi × 0.0689476. This works because 1 psi equals approximately 0.0689476 bar. To convert, you multiply the psi value by this factor, which scales the pressure appropriately in metric units.
For example, with 2.5 psi: 2.5 × 0.0689476 = 0.1724 bar. Each psi is multiplied by 0.0689476 to get the bar equivalent, making it a simple linear calculation for any value of psi.
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 4.5 psi to bar:
- Multiply 4.5 by 0.0689476
- 4.5 × 0.0689476 = 0.3103 bar
- Convert 7.8 psi to bar:
- Multiply 7.8 by 0.0689476
- 7.8 × 0.0689476 = 0.5377 bar

Conversion Definitions
psi
Psi, or pounds per square inch, is a unit of pressure measurement in imperial units representing the force of one pound applied over an area of one square inch, commonly used in the US for tire pressures and other pressure-related measurements.
bar
Bar is a metric unit of pressure equal to 100,000 pascals, used internationally especially in Europe and in scientific contexts, to measure force per unit area, mainly in meteorology, engineering, and industrial applications.
Conversion FAQs
How accurate is the conversion from 2.5 psi to bar?
The conversion from 2.5 psi to 0.1724 bar is precise based on the fixed conversion factor 0.0689476. Minor differences can occur with rounding, but for practical purposes, this value is sufficiently accurate for most applications.
Can I use the same formula for converting other psi values to bar?
Yes, the same formula applies universally: bar = psi × 0.0689476. Just replace the psi value with your specific measurement to get the corresponding bar value, making it a straightforward calculation for any pressure reading.
Why is the conversion factor 0.0689476 used?
This factor is derived from the exact relationship between psi and bar, where 1 psi equals 0.0689476 bar, based on the definitions of both units and their equivalence in force per area.
