PSI to Bar Online

Updated 2026-07-26

Convert PSI to bar online for free. Enter a pressure in PSI and SnapTools shows the exact value in bar instantly, in your browser — nothing is uploaded.

Tire pressure is the classic case: US and UK gauges read PSI, while most of continental Europe and a lot of workshop equipment reads bar — so a 32 PSI spec means nothing on a bar gauge until it's converted. This tool uses the exact 0.0689475729 factor, not a rounded approximation. For the full family of pressure units — pascals, atmospheres, mmHg — use the Pressure Converter.

// how to use

  1. 1 Type or paste a pressure in PSI into the input.
  2. 2 SnapTools converts it to bar as you type.
  3. 3 Copy the result, or use the slider for a quick scrub across common tire/gauge ranges.

Is my input uploaded to a server?
No. The conversion runs entirely in your browser, so nothing you enter leaves your machine.
Why would I need this for tire pressure?
US and UK tire gauges read in PSI; most of continental Europe and many workshop compressors read in bar. This converter lets you match the number on your gauge to the spec on your tire or in your manual.
What's the exact conversion factor?
1 PSI is exactly 0.0689475729 bar. This tool uses the full-precision figure, not a rounded 0.069.
Is bar the same as "atmospheres"?
Close but not identical — 1 bar is about 0.987 atmospheres. The full Pressure Converter offers atmospheres and mmHg (torr) as separate units if you need those exactly.
What about converting bar back to PSI?
Use Bar to PSI, or the full Pressure Converter for pascals, atmospheres, and mmHg.
