Convert psi to bar
To convert psi to bar, multiply the value in psi by 0.0689476 (exactly 6,894.757293168 ÷ 100,000). Drivers check tyre pressures with it, and divers, home brewers and compressor owners compare gauges marked in psi and bar. This psi to bar converter works both ways: type psi or bar into either box above and the other box, the worked formula and the chart below update as you type.
Pounds per square inch (psi) is the pressure of one pound-force pressing on one square inch — exactly 6,894.757293168 pascals. It is used for tyre pressures in the US and UK, air compressors, pressure washers, scuba cylinders and hydraulics. One pound per square inch is 0.0689476 bar.
The bar is a metric unit of pressure equal to exactly 100,000 pascals (100 kPa) — very close to average air pressure at sea level, which is 1.01325 bar. Going the other way, one bar equals 14.5038 pounds per square inch. Bar is used for tyre pressures in Europe and many other regions, espresso machines, pressure washers, dive cylinders and, as millibars, on weather maps.
How to convert psi to bar with this tool
- Type a number into the Pounds per square inch (psi) box — it starts at 32 psi as an example.
- Read the answer in the Bar box and in the result panel, which also shows the formula with your number.
- To go the other way, type into the bar box, or press the swap button to open the Bar to PSI converter with your value carried over.
- Choose how many decimal places you want, or tap a quick value such as 14.7 psi, 30 psi, 32 psi.
- Press Copy result to paste the conversion into a message, spreadsheet or note.

Converts both ways
Type in the psi box to get bar, or in the bar box to get psi. The other box follows instantly.
Exact factor
Calculations use 1 psi = 0.06894757293168 bar, and rounding is applied only to the answer you see — choose Auto or 0–10 decimal places.
Formula with your number
The working is shown under the result, for example 32 psi × 6,894.757293168 ÷ 100,000 = 2.2063 bar, so you can check it or copy the method.

Tap common values like 14.7 psi, 30 psi, 32 psi, or read the psi-to-bar table further down this page.
Kilopascals as well
Many tyre placards and gauges also use kPa, so the kilopascal value is shown under the bar result.
PSI to Bar formula
The formula is bar = psi × 6,894.757293168 ÷ 100,000. It is exact because one psi is exactly 6,894.757293168 pascals and one bar is exactly 100,000 pascals.
The reverse formula is psi = bar × 100,000 ÷ 6,894.757293168 — or use the Bar to PSI converter. Three worked examples:
- A car tyre at 32 psi: 32 psi × 6,894.757293168 ÷ 100,000 = 2.2063 bar
- A 3,000 psi scuba cylinder: 3,000 psi × 6,894.757293168 ÷ 100,000 = 206.8427 bar
- Atmospheric pressure (14.7 psi): 14.7 psi × 6,894.757293168 ÷ 100,000 = 1.0135 bar
PSI to Bar quick reference
The values people look up most often, worked out with the exact factor:
- 1 psi = 0.0689476 bar
- 1 bar = 14.5038 psi
- 14.7 psi = 1.0135 bar
- 30 psi = 2.0684 bar
- 32 psi = 2.2063 bar
- 35 psi = 2.4132 bar
Quick tip: Divide by 14.5 for a quick estimate: 29 psi ≈ 2 bar, versus the exact 1.9995 bar.

PSI to Bar FAQ
What is 35 psi in bar?
35 pounds per square inch is 2.4132 bar: 35 psi × 6,894.757293168 ÷ 100,000 = 2.4132 bar.
How do I convert psi to bar?
Multiply the value in psi by 0.0689476 (exactly 6,894.757293168 ÷ 100,000). For example, 100 psi × 6,894.757293168 ÷ 100,000 = 6.8948 bar. To convert back, multiply the value in bar by about 14.5038 (exactly 100,000 ÷ 6,894.757293168) — or use the Bar to PSI converter.
What is 1 bar in psi?
One bar is 14.5038 pounds per square inch, because 1 bar × 100,000 ÷ 6,894.757293168 = 14.5038 psi.
What does 100 psi equal in bar?
What is psi in kPa?
Multiply by 6.894757: 32 psi is about 220.6 kPa. Since 1 bar = 100 kPa, that is the same pressure as 32 psi = 2.2063 bar. The kPa value is shown under the result.
