Conversion Formula
The conversion from bar to psi works by multiplying the number of bars by 14.5038, because 1 bar equals 14.5038 psi. This formula is based on the defined relationship between these two units of pressure measurement. For example, for 3.8 bar: 3.8 × 14.5038 = 55.11 psi.
By applying this multiplication, pressure readings in bar are translated into psi, enabling compatibility with systems and contexts that measure pressure in pounds per square inch. The formula’s accuracy depends on the precision of the conversion factor used.
Conversion Example
- Convert 5 bar to psi:
- Step 1: Take 5 (bar)
- Step 2: Multiply 5 × 14.5038
- Step 3: Result is 72.519 psi
- Convert 2.5 bar to psi:
- Step 1: Start with 2.5
- Step 2: Multiply 2.5 × 14.5038
- Step 3: Result equals 36.2595 psi
- Convert 10 bar to psi:
- Step 1: Use 10
- Step 2: 10 × 14.5038
- Step 3: Equals 145.038 psi

Conversion Definitions
Bar
A bar is a metric unit of pressure equal to 100,000 pascals, roughly the pressure exerted by a 1-liter container of water at a height of 10 meters. It is used in meteorology and engineering for measuring atmospheric and system pressures.
Psi
Pounds per square inch (psi) measures pressure by the force in pounds applied to an area of one square inch. It is common in the United States for tire pressures, hydraulic systems, and other applications requiring pressure measurement.
Conversion FAQs
What is the best way to quickly convert 3.8 bar to psi?
Multiply 3.8 by 14.5038, which gives approximately 55.11 psi, providing an immediate and accurate conversion without needing additional tools.
Why is the conversion factor between bar and psi 14.5038?
This factor is based on the definition that 1 bar equals exactly 100,000 pascals, and since 1 psi equals 6894.76 pascals, dividing these gives 14.5038, establishing the precise relationship between the units.
Can I use a rough estimate instead of the exact conversion?
Yes, for quick calculations, you can approximate 1 bar as 14.5 psi, which is close enough for most practical purposes, but for precise measurements, use the full conversion factor.
What tools are best for converting between bar and psi?
Online calculators, digital pressure conversion tools, and embedded JavaScript converters like the one above are reliable for quick and accurate conversions.
