Unit relationship
Formula
psi = Pa ÷ 6894.757293168361 (1 bar = 100000 Pa)= 31.908302300646
Note
This result is a simplified model: it converts the single value you entered with the exact factors shown, and rounds to the display precision. It does not know your measurement's accuracy, and cooking or density conversions depend on how an ingredient is packed. Check critical figures against the original units.

How many psi are in a bar?+
One bar equals approximately 14.5038 psi (pounds per square inch). The calculator uses this precise factor, which comes from bar being defined as exactly 100,000 pascals and psi being defined via the pound-force and square inch.
What is kPa and how does it relate to bar and psi?+
A kilopascal (kPa) is 1,000 pascals, and since 1 bar = 100,000 pascals = 100 kPa, converting bar to kPa is simply multiplying by 100. This calculator shows kPa alongside psi since many pressure gauges (especially in Europe) are marked in kPa or bar rather than psi.
Why do tire pressure recommendations look so different between a US car (psi) and a European one (bar)?+
They're just different units for the same physical quantity — a typical car tire at 2.2 bar is about 32 psi. Always confirm which unit your gauge reads before comparing it to a manufacturer's recommended pressure.
Is atmospheric pressure close to 1 bar?+
Yes, standard atmospheric pressure at sea level is defined as 101,325 pascals, which is very close to 1 bar (100,000 pascals) — about 1.01325 bar, or roughly 14.7 psi, which is why 1 bar is a convenient everyday reference point for 'normal' pressure.
Why does a small error in bar reading translate to a larger-looking psi error?+
Because 1 bar spans about 14.5 psi, any measurement uncertainty gets multiplied by roughly 14.5 when converted, so a gauge reading with ±0.05 bar of uncertainty translates to roughly ±0.7 psi of uncertainty — worth keeping in mind for precision applications like pneumatic tools.
