PSI to Bar (psi to bar)
Result
0.06894757293 Bar
Formula
bar = psi × 0.06894757293
1 psi = 0.06894757293 bar, and 1 bar = 14.50377377 psi.
The pascal is one newton per square metre. The bar is exactly 100,000 Pa, the standard atmosphere exactly 101,325 Pa, the torr exactly 1/760 atm, and psi is one pound-force per square inch (6,894.757 Pa).
Worked examples
- 14.7 psi × 0.06894757293 = 1.0135293 bar
- 30 psi × 0.06894757293 = 2.0684272 bar
- 32 psi × 0.06894757293 = 2.2063223 bar
- 100 psi × 0.06894757293 = 6.8947573 bar
Things to know about psi to bar
- Multiply by 0.0689476. A 32 psi tyre pressure is 2.21 bar.
- Tyre gauges show gauge pressure (above atmospheric), so 32 psi on the gauge is about 46.7 psi absolute.
