Bar to PSI Online

Updated 2026-10-24

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

Equipment manuals and tire specs from continental Europe are usually in bar, but US and UK gauges read PSI, so a "2 bar" spec needs converting before it means anything on your gauge. This tool uses the exact 14.5037737797 factor, not a rounded 14.5. 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 bar into the input.
  2. 2 SnapTools converts it to PSI as you type.
  3. 3 Copy the result, or use the slider for a quick scrub across common gauge ranges.

// faq

Should I use PSIG or PSIA for this conversion?
Almost always PSIG (gauge pressure), which is what tire gauges, compressors, and most equipment specs report - it measures relative to atmospheric pressure, so a flat tire reads 0 PSIG. PSIA (absolute pressure) includes atmospheric pressure itself and matters mainly for vacuum systems and true scientific measurement; at sea level, 0 PSIG equals about 14.7 PSIA.
Why would I convert bar to PSI?
If your equipment manual or tire spec is in bar but your gauge (US/UK-made) reads PSI, converting the target figure lets you inflate or check to the right number.
What's the exact conversion factor?
1 bar is exactly 14.5037737797 PSI, the reciprocal of the exact 0.0689475729 bar per PSI.
Is bar the same as "atmospheres"?
Close but not identical. 1 bar is about 0.987 atmospheres, not exactly one. The full Pressure Converter offers atmospheres separately if you need the exact figure.
What about converting PSI back to bar?
Use PSI to Bar, or the full Pressure Converter for pascals, atmospheres, and mmHg.
