1. How to convert bar to psi
The conversion is a single multiplication: psi = bar × 14.503773773. Both units are defined
against the same base — the pascal (Pa) — so the factor is fixed and the result
is exact to the precision shown.
Worked at the two values people ask for most: 1 bar = 14.503774 psi and
32 bar = 464.12076 psi. Going the other way, bar = psi × 0.0689475729317, so
1 psi = 0.068947573 bar — a direction with its own page, psi to bar.
Results are given to eight significant figures. That is more precision than most jobs need — for a rough figure, treat 1 bar as about 14.503774 psi and adjust — but rounding early and multiplying afterwards is how a small error becomes a visible one, so the full figure is what the converter carries.

Every row is the same factor applied — nothing in the table is a special case, and any value in between behaves the same way. Type your own figure into the converter above and the Formula tile shows the arithmetic being used, so the result is checkable rather than taken on trust.
3. What the two units are
- Bar (bar). One bar is 100,000 Pa.
- Pounds per square inch (psi). One psi is 6,894.7573 Pa.
Both are converted through the pascal (Pa): the value is multiplied by its own unit's factor to reach the base, then divided by the target unit's factor to leave it. No direct bar to psi factor has to exist or be kept correct, which is also why the converter can show the same value in all 10 pressure units at once.
Pressure converts through the pascal, which is one newton per square metre and a very small unit — hence the kilopascal and the bar (exactly 100,000 Pa) in practical use. One standard atmosphere is exactly 101,325 Pa. Whether your figure is absolute or gauge pressure is a property of the instrument, not of the arithmetic.
If the pair you actually want is not this one, the full unit converter runs every 10 pressure units off the same factor table, along with 11 other categories of measurement.
4. Bar to Pounds per square inch FAQs
How do I convert bar to psi?
Multiply by 14.503773773. 1 bar = 14.503774 psi, and 32 bar = 464.12076 psi. The factor is exact to the precision shown, so the only rounding is the one you choose to do at the end.
How many psi is 1 bar?
1 bar = 14.503774 psi. The full formula is psi = bar × 14.503773773, and 1 psi = 0.068947573 bar going the other way.
What is 32 bar in psi?
32 bar = 464.12076 psi. The table above works the same factor through 9 values, and the converter takes any figure you type — including decimals.
How do I convert psi to bar?
bar = psi × 0.0689475729317, so 1 psi = 0.068947573 bar. Use the Swap button in the converter to reverse the direction without retyping the value, or open the dedicated psi to bar page.
Is this gauge or absolute pressure?
Whichever your figure already is. The conversion changes the unit, not the reference point — a gauge reading converts to a gauge reading. One standard atmosphere is exactly 101,325 Pa, and a bar is exactly 100,000 Pa, so 1 bar is 0.98692 atm.
Is anything I type sent to a server?
No. The factor table ships with the page and every conversion runs in your browser. Nothing is uploaded, logged or written to storage, and the converter keeps working offline once the page has loaded.
