Going the other way? Use the bar to psi converter.
Your US car says to run the tires at 35 psi, but you’re using a European pump that only reads bar. What number do you aim for? About 2.41 bar. This converter does that translation the instant you type, so you’re not guessing at the air pump.
The factor is fixed: 1 psi = 0.0689476 bar. Multiply psi by roughly 0.069 and you’ve got bar. So 30 psi is 2.07 bar, 32 psi is 2.21 bar, and 40 psi is 2.76 bar. Small numbers in bar, which is exactly why the unit trips up anyone used to psi.
US tire pressures in bar
This is the conversion most people actually want. American passenger-car specs almost always sit between 30 and 36 psi, and that whole band collapses into a narrow slice of bar: 30 psi is 2.07 bar, 35 psi is 2.41 bar, and 36 psi is 2.48 bar. So the 32 to 35 psi window on most US door jambs works out to roughly 2.2 to 2.4 bar. Handy when a tire shop abroad, or a metric gauge, won’t speak psi. The table above spells out every psi value across that range, and the free field takes anything else.
Beyond tires
Tires are the headline, but psi-to-bar shows up elsewhere too. Pressure washers are rated in psi in the US (a 2000 psi unit is about 138 bar), and air compressors, bike pumps with US gauges, and some industrial equipment all default to psi. If your manual or replacement gear is metric, converting keeps the numbers consistent. Bike tires in particular swing wildly: a road tire at 100 psi is 6.9 bar, while a mountain bike at 30 psi is 2.07 bar, and getting that right matters for grip and ride feel.
Under the hood
Why such an awkward decimal? Because psi and bar come from completely different measurement traditions. One psi is the pressure of a single pound-force pressing on one square inch, an imperial definition. One bar is 100,000 pascals, anchored to the metric system. Convert between them and a psi works out to 0.0689476 bar exactly, no clean round number in sight. There’s no offset to worry about, unlike temperature, so the tool just multiplies by that exact factor. Type a psi value and the bar result updates live as you go.
All the math runs in your browser. Nothing you type gets uploaded, and the converter keeps working with no connection once the page has loaded.
Questions
What is 35 psi in bar?
2.41 bar. Since 35 psi is one of the most common US tire pressures, it’s a frequent lookup. The tool gives the exact figure for any psi value you enter.
How many bar is 32 psi?
2.21 bar. The typical US car tire range of 32 to 35 psi works out to roughly 2.2 to 2.4 bar.
What is 40 psi in bar?
2.76 bar. Full-size trucks and loaded vans often want 40 psi or a touch more on the rear axle, which lands just under 2.8 bar.
How many bar is 100 psi?
6.89 bar. That’s road-bike territory, not cars: a narrow 25mm road tire pumped to 100 psi runs 6.89 bar, though riders on wider rubber have mostly dropped toward 70 to 80 psi.
What’s the conversion factor?
1 psi = 0.0689476 bar. The tool applies this exact value, so results are precise rather than rounded to two decimals.
Why is the bar number so much smaller?
Because bar is a much larger unit. One bar is about 14.5 psi, so converting the other direction shrinks the number. A 35 psi tire is only 2.41 bar, even though it’s the same physical pressure.
Does this calculate offline?
Yes. It’s pure browser-side math with a fixed factor, so your values stay on your device and it runs without internet after the page loads.
