Conversion Formula
The formula to convert bar to psi is: psi = bar × 14.5038. This works because 1 bar equals exactly 14.5038 pounds per square inch. For example, to convert 3.3 bar: 3.3 × 14.5038 = 47.87 psi. This multiplication adjusts the pressure units from metric to imperial system accurately.
Conversion Example
- Convert 5 bar to psi:
- Step 1: Write formula: psi = 5 × 14.5038
- Step 2: Multiply: 5 × 14.5038 = 72.519 psi
- Step 3: Result: 5 bar equals 72.52 psi (rounded to two decimals)
- Convert 1.5 bar to psi:
- Step 1: Write formula: psi = 1.5 × 14.5038
- Step 2: Multiply: 1.5 × 14.5038 = 21.7557 psi
- Step 3: Result: 1.5 bar equals 21.76 psi
- Convert 10 bar to psi:
- Step 1: Write formula: psi = 10 × 14.5038
- Step 2: Multiply: 10 × 14.5038 = 145.038 psi
- Step 3: Result: 10 bar equals 145.04 psi

Conversion Definitions
Bar
A bar is a metric unit of pressure equivalent to 100,000 pascals, used to measure force per unit area, especially in meteorology and engineering to denote atmospheric or system pressures.
Psi
Pounds per square inch (psi) is an imperial pressure unit representing force in pounds applied over one square inch of area, widely used in the United States for tire pressure, hydraulics, and industrial systems.
Conversion FAQs
Why is the conversion factor 14.5038 for bar to psi?
This factor is derived from the exact equivalence where 1 bar equals 100,000 pascals, and 1 psi is approximately 6,894.76 pascals. Dividing 100,000 by 6,894.76 yields roughly 14.5038, which converts bar to psi accurately.
Can I convert negative bar values to psi?
Yes, negative bar values represent vacuum or pressure below atmospheric pressure. Multiplying negative values by 14.5038 gives the corresponding negative psi, indicating a vacuum state.
Is this conversion accurate for all pressure ranges?
The formula is accurate within the standard pressure ranges used in engineering and meteorology. However, extremely high or low pressures beyond typical application might require specialized calculations or units.
How does temperature affect the pressure conversions?
Temperature can affect pressure measurements, but the conversion between bar and psi remains the same mathematically. Variations in temperature influence the actual pressure readings but not the unit conversion formula itself.
Can I convert from psi back to bar using the same formula?
Yes, reversing the process involves dividing psi by 14.5038. For example, to convert 47.87 psi back to bar: 47.87 / 14.5038 = 3.3 bar.
