Quick Summary

Use this when you need:

Check automotive or bicycle tire specs listed in bar against shop gauges in psi
Convert hydraulic system setpoints from bar into psi for North American teams
Translate refrigeration service charts that mix bar, kPa, and psi

You’ll get:Pressure

How this is calculated

Formula:

pressure_target = pressure_source

In plain language:

The converter normalizes pressures to Pascals using 1 bar = 100,000 Pa and 1 psi = 6,894.757 Pa, then expresses them in bar, psi, or kilopascals.

The formula is always visible so you can verify the math and explain your numbers to anyone who asks.

Bar to psi converter explained

Hydraulics, HVAC, and automotive tools often swap between bar and psi. This calculator converts both ways and shows kPa and Pa for engineering clarity.

How the conversion works

One bar equals $100{,}000\,\text{Pa}$ ; one psi equals $6{,}894.757\,\text{Pa}$ . Conversions use those anchors:

P_{\text{psi}} = P_{\text{bar}} \times \frac{100{,}000}{6{,}894.757} \approx P_{\text{bar}} \times 14.5038

P_{\text{bar}} = P_{\text{psi}} \times 0.0689476

Units and conversions

Unit	Symbol	Relation to Pa
Bar	bar	$1\,\text{bar} = 100{,}000\,\text{Pa}$
PSI (absolute)	psi	$1\,\text{psi} = 6{,}894.757\,\text{Pa}$
Kilopascal	kPa	$1\,\text{kPa} = 1{,}000\,\text{Pa}$
Pascal	Pa	base unit

Worked examples

Shop air in bar → psi
Given $7.0\,\text{bar}$ :
$P_{\text{psi}} = 7.0 \times 14.5038 \approx 101.53\,\text{psi}$
Result: 101.5 psi.
Tire pressure in psi → bar
Given $60\,\text{psi}$ :
$P_{\text{bar}} = 60 \times 0.0689476 \approx 4.14\,\text{bar}$
Result: 4.14 bar.

Tips and pitfalls

Distinguish psig from psia; this tool treats psi as absolute. Add atmospheric pressure (≈14.7 psi) to gauge readings before converting if you need absolute.
Metric drawings often call for kPa; use the kPa card for compliance reports.
Do not round early; small rounding at high pressures can exceed instrument tolerances.
